Region setting keeps reverting to default after update (AWS Bedrock – eu-west-3)

[Julien_Cruau]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

We are using AWS Bedrock in the eu-west-3 region. Since the latest update, the region setting in Cursor no longer persists and keeps reverting to the default value (eu-east-2 / eu-east-3 depending on the UI).

Impact:
Prevents stable use of AWS Bedrock in the correct region and interrupts workflow.

Steps to Reproduce

Change the region setting to eu-west-3.

Send a message or generate a plan in the chat → Works correctly.

Send another message → Fails, because the region has automatically reverted in the configuration (the UI shows eu-east-2 or eu-east-3 again).

Expected Behavior

The selected region (eu-west-3) should persist across messages and not revert automatically.

Operating System

MacOS

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey, thanks for the report.

This is clearly a bug - the region shouldn’t reset after each message.

To help the team fix it faster, please add:

• Logs from the Developer Tools Console (Help > Toggle Developer Tools > Console) captured while the region switches

I’ll pass this to the team.

Hi Dean,
Thank you for your reply.
Some update : actually, the region self reset automatically after a few seconds.

[deanrie]

Thanks for the logs. I’ve passed everything to the dev team with full details. The fact that the region resets automatically after a few seconds (not only after sending a message) should help them pinpoint the root cause faster.

[Julien_Cruau]

Fixed with the last release !
