agc workflow run fails to upload input.json saying its parent directory is a directory

[biofilos]

Environment:
Content of agc-project.yaml

name: wf
schemaVersion: 1
contexts:
  onDemand:
    engines:
      - type: wdl
        engine: cromwell

  spot:
    requestSpotInstances: true
    engines:
      - type: wdl
        engine: cromwell

data:
  - location: s3://some-bucket

workflows:
  variantCall:
    type:
      language: wdl
      version: 1.0
    sourceURL: variantCall

Contents of the directory variantCall

main.wdl
modules.zip

In the same directory as agc-project.yaml, there is a file called variantCall.inputs.json

When I run agc workflow run -c spot variantCall -i variantCall.inputs.json, this is the error I get

/home/alekos/Documents/nus/projects/scalable-workflows/aws_cli/ is the directory where agc-project.yaml and variantCall.inputs.json is

I can run the read example in the agc examples directory. I have also tried renaming all files, and including manifest.json. Even though it is far from desired, I have also hard-coded the input.json in the manifest.json (with and without specifying the input.json through --inputsFile), but got the same result

Is there anything I am missing? How can I troubleshoot this?

Thank you

bug reported to team. While this gets fixed, just avoid using empty strings "" in inputs.json
