This issue might be a duplicate of existing issues. Please check:
All of these appear to be caused by the agents array not being properly initialized during startup or remote attach scenarios. Feel free to ignore if your specific case differs from these.

Closing as duplicate of #7918. This is the same root cause - agents array is empty or not loaded during startup. The tracking issue #7918 has root cause analysis.
