'NoneType' object has no attribute 'split'

Hi, I am currently using Stitchdata for Gitlab integration. After a few days of running smoothly, I suddenly got this error message: 'NoneType' object has no attribute 'split'. And the pipeline has not been working ever since. We haven't really made any changes on Git so I am not sure what caused the issue. Could anyone please advice? Thanks

Target succeeded.

Start in tap_gitlab/init.py at do_sync(), especially the CONFIG['groups'].split(' ') traceback location. Reproduce with the reported configuration and inspect how groups is populated before the split. Done means the pipeline handles this configuration without the shown AttributeError, with a test covering the behavior.
