XMLHttpRequest is not defined

[Belephor92]

Subject of the issue

When calling this.client.request(new SessionStartAction(authData)) I receive the error "XMLHttpRequest is not defined"
I checked the configuration with the start Kultura Session guide from the workflow section and the connection itself should work.

Your environment

• kaltura-typescript-version: 16.5
• nest-js project environment
• Package manager: npm

Steps to reproduce

Set up the library as described in https://developer.kaltura.com/workflows/Generate_API_Sessions/Authentication;step=1

Expected behaviour

I should receive the token

Actual behaviour

I get following error:
ReferenceError: XMLHttpRequest is not defined

at Injector.loadInstance (C:\Career Partner\Projects\idss-discovery\node_modules@nestjs\core\injector\injector.js:81:9)

I tried adding XMLHttpRequest manually using npm install to the project and added it as dependency in util.js in my node_modules.
The error disappeard but when starting the connection I get another error: KalturaclientException that contains the correct response token. I guess this behavior comes from the manually installed XMLHttpRequest package.

Do you have any idea how to fix my problem?

Thanks in advance,

best regards,

Hi @Belephor92,

Thank for you reporting an issue and helping improve Kaltura!

To get the fastest response time, and help the maintainers review and test your reported issues or suggestions, please ensure that your issue includes the following (please comment with more info if you have not included all this info in your original issue):

• Is the issue you're experiencing consistent and across platforms? or does it only happens on certain conditions?
  please provide as much details as possible.
• Which Kaltura deployment you're using: Kaltura SaaS, or self-hosted?
  If self hosted, are you using the RPM or deb install?
• Packages installed.
  When using RPM, paste the output for:

	# rpm -qa \"kaltura*\"

For deb based systems:

	# dpkg -l \"kaltura-*\"

• If running a self hosted ENV - provide the MySQL server version used
• If running a self hosted ENV - is this a single all in 1 server or a cluster?
• If running a self hosted ENV, while making the problematic request, run:

	# tail -f /opt/kaltura/log/*.log /opt/kaltura/log/batch/*.log | grep -A 1 -B 1 --color \"ERR:\|PHP\|trace\|CRIT\|\[error\]\"

and paste the output.

• When relevant, provide any screenshots or screen recordings showing the issue you're experiencing.

For general troubleshooting see:

Thank you in advance,

This is rather a bug than a question.
The XMLHttpResponse is a missing dependency as I assume. This has to be fixed.

Hi @Belephor92! I am experiencing the same issue as you.
Did you ever get it solved somehow?
Thanks for your feedback!

Hi @shugli,
I think the problem was how we built up the request. I had a look at our current working code for you.

async checkSession() {
      this.logger.verbose('checking session');
      await kaltura.services.user
        .get(kalturaConfig.USER_ID)
        .execute(this.client)
        .then((result) => {
          this.logger.verbose('session active');
        }, (error) => {
          this.logger.warn('session has to be restarted');
          this.startKalturaSession();
          return new Promise((resolve) => setTimeout(resolve, 1000)); // wait a second for session to be started
        });
    }

    startKalturaSession() {
      this.logger.verbose('trying to start kaltura session');
      kaltura.services.session
        .start(
          kalturaConfig.ADMIN_SECRET,
          kalturaConfig.USER_ID,
          kaltura.enums.SessionType.ADMIN,
          kalturaConfig.PARTNER_ID,
          kalturaConfig.EXPIRY,
          'appId:appName-appDomain',
        )
        .completion((success, ks) => {
          if (!success) throw new Error(ks.message);
          this.client.setKs(ks);
          kaltura.services.user
            .get(kalturaConfig.USER_ID)
            .execute(this.client)
            .then((result) => {
              this.logger.verbose('kaltura session started');
            });
        })
        .execute(this.client);
    }

The startKalturaSession function starts the session.
Before every call I use the checkSession function in order to revalidate the token.

Here is an example for a call that we do:

    public async executeESearch(searchFilters: {searchTerm: string, courseCode: string, pageSize?: number}) {
      await this.checkSession();
      const searchTerm = SearchUtil.replaceUmlaute(searchFilters.searchTerm);
      this.logger.verbose(`starting ESearch for course ${searchFilters.courseCode} with term ${searchTerm}`);
      const searchParams = new kaltura.objects.ESearchEntryParams();
      searchParams.searchOperator = new kaltura.objects.ESearchEntryOperator();
      searchParams.searchOperator.operator = kaltura.enums.ESearchOperatorType.OR_OP;
      searchParams.searchOperator.searchItems = [];

      // courseCode search in metadata
      searchParams.searchOperator.searchItems[0] = new kaltura.objects.ESearchEntryMetadataItem();
      searchParams.searchOperator.searchItems[0].metadataProfileId = someIntForMetadata;
      searchParams.searchOperator.searchItems[0].xpath = 'wont show here'
      searchParams.searchOperator.searchItems[0].addHighlight = false;
      searchParams.searchOperator.searchItems[0].itemType = kaltura.enums.ESearchItemType.EXACT_MATCH;
      searchParams.searchOperator.searchItems[0].searchTerm = searchFilters.courseCode;

      // AND
      searchParams.searchOperator.searchItems[1] = new kaltura.objects.ESearchEntryOperator();
      searchParams.searchOperator.searchItems[1].operator = kaltura.enums.ESearchOperatorType.OR_OP;
      searchParams.searchOperator.searchItems[1].searchItems = [];

      // in Name
      searchParams.searchOperator.searchItems[1].searchItems[0] = new kaltura.objects.ESearchEntryItem();
      searchParams.searchOperator.searchItems[1].searchItems[0].searchTerm = searchTerm;
      searchParams.searchOperator.searchItems[1].searchItems[0].itemType = kaltura.enums.ESearchItemType.PARTIAL;
      searchParams.searchOperator.searchItems[1].searchItems[0].addHighlight = false;
      searchParams.searchOperator.searchItems[1].searchItems[0].fieldName = kaltura.enums.ESearchEntryFieldName.NAME;

      // or Description
      searchParams.searchOperator.searchItems[1].searchItems[1] = new kaltura.objects.ESearchEntryItem();
      searchParams.searchOperator.searchItems[1].searchItems[1].searchTerm = searchTerm;
      searchParams.searchOperator.searchItems[1].searchItems[1].itemType = kaltura.enums.ESearchItemType.PARTIAL;
      searchParams.searchOperator.searchItems[1].searchItems[1].addHighlight = false;
      searchParams.searchOperator.searchItems[1].searchItems[1].fieldName = kaltura.enums.ESearchEntryFieldName.DESCRIPTION;

      // or Tags
      searchParams.searchOperator.searchItems[1].searchItems[2] = new kaltura.objects.ESearchEntryItem();
      searchParams.searchOperator.searchItems[1].searchItems[2].searchTerm = searchTerm;
      searchParams.searchOperator.searchItems[1].searchItems[2].itemType = kaltura.enums.ESearchItemType.PARTIAL;
      searchParams.searchOperator.searchItems[1].searchItems[2].addHighlight = false;
      searchParams.searchOperator.searchItems[1].searchItems[2].fieldName = kaltura.enums.ESearchEntryFieldName.TAGS;

      const pager = new kaltura.objects.Pager();
      pager.pageSize = searchFilters.pageSize ?? 50;

      return kaltura.services.eSearch
        .searchEntry(searchParams, pager)
        .execute(this.client)
        .then(
          (result) => result,
          (err) => {
            this.logger.error(err);
            return err;
          },
        );
    }

Thanks @Belephor92 !

But are you still using the Typescript client lib? Because this looks more like the nodeJS implementation, or?

Ok, solution proposed in tensorflow/tfjs#514 (comment) actually did the job!!!!
