Error when launching Zetane: "[json.exception.parse_error.101] parse error at 1: syntax error - invalid literal; last read: '<'"

[hadoop78]

Hello,

When I try to launch Zetane, I encounter the following error message:

[json.exception.parse_error.101] parse error at 1: syntax error - invalid literal; last read: '<'

I am unsure what this error means or how to resolve it. It seems like a parsing issue related to JSON input, but I don't know where the problem originates.

What causes this error?
Is there any way to fix it on my end?
Are there specific files or configurations that might be causing this?
Any help would be greatly appreciated. Thank you!
