Describe the issue:

I'm on dev.palm

When trying to use Claude 3.7 Bedrock with Assistant, it errors out. Cluade 3.5 works without issue

Steps to reproduce the issue:

Expected or desired behavior:

No errors

Were there any error messages in the UI, Output panel, or Developer Tools console?

I experienced the same on dev.palm. Claude 3.5 worked but not 3.7. Oddly, it did work for me on desktop.

I just tried it on dev.palm and it works now. It's the same version that I tried before (2025.06.0-107)

[sharon-wang]

Bedrock is working for me on Workbench across the Claude models except for Claude 4 Opus -- I am seeing https://github.com/posit-dev/positron/issues/7844.

Models

Moving to verification as the AccessDeniedException may be resolved now? 🤞
