Hmm I was not able to reproduce this.. I tried running a vanilla ADK agent with all the instrumentation env vars and dependencies set as per the docs but with fsspec and gcsfs to 2026.2.0 and the upload worked.

Good to close folks?

We can close it for now, I will re-open the ticket if I run into the issue again.

SG... I did make a change to verify the upload works at startup, and if it doesn't to fail, instead of repeatedly failing each upload: #4390 -- also it could be the env var wasn't prefixed with gs:// - that is required to upload to GCS.. I don't know if that could have caused this stacktrace or not..
