Try Using a File Uploaded During Grounding Setup
Instead of picking an existing bucket file:
- Go to Context Grounding > Add Indexed File
- Upload the testfile.pdf right there from your machine, instead of choosing from bucket
If this works: ➜ problem is with Storage Bucket access by ECS, not the file or ECS.
Test with a Different Storage Bucket
- Create a new Storage Bucket in the same folder.
- Upload a simple test PDF.
- Reconfigure grounding with that file.
If this works: ➜ your original bucket has a hidden permission or scope problem.
Use the “Upload and Index” Option**
If available, use:
- “Upload and Index” → upload the file from local storage rather than selecting from an existing bucket.
This is known to bypass some of the token-based fetch failures from Storage Bucket access.
Contact UiPath Support with Session ID
If all else fails:
- Provide the telemetry session ID:
E+4cHYIR9IDDOSUP3/UcS/
And explain that it fails only when using indexed files from Storage Buckets.
