I tried on a couple different boxes:

And via the Python script:

pip install -r requirements.txt
...

export URBACKUP_SERVER_URL=http://192.168.1.87:55414/

python urbackup-exporter.py

Aha, I figured it out... I have an ! in my password and the script cannot handle that. :|

Once I escaped it the script is fine but that didn't fix the Docker version. I'll change my password to something without such a special character. :)

You can open a pr to fix the issue if you want to.

Am having the same issue but changing the password not to include special characters still doesn't fix the issue on the Docker container, unless I'm doing something wrong.

[DustyArmstrong]

The suggested fix is to use single quotes ' ' due to the way Linux handles environment variables. This would disable string substitution. I can do a PR but I'm of course not that familiar with the project.

I was stumbling on the same issue, turns out to be user error. Forgetting to include the easily-forgettable /x API path to the UrBackup server means that the JSON decoder will be ingesting non-JSON content. Ideally the urbackup-server-web-api-wrapper package should implement a defensive format verification, alas that package seems to be stale.

So, do make sure that you provide:
URBACKUP_SERVER_URL=http://192.168.1.87:55414/x

not:
URBACKUP_SERVER_URL=http://192.168.1.87:55414/
