Bedrock – Fable 5: Unable to reach the model provider

I’m getting this error now:

The model returned the following errors: data retention mode 'default' is not available for this model

This is after setting data retention to provider_data_shareand verifying that fable is working via direct bedrock calls.

Hi @Raman_Varma, good news and useful news here.

The error changing is actually confirmation that yesterday’s fix is live: your requests are now reaching Bedrock correctly. This new message is coming straight from AWS, not from Cursor. Fable 5 on Bedrock only permits the provider_data_share data retention mode, and AWS resolves the effective mode from your account/project configuration per region. Cursor doesn’t send any retention setting in the request, so it can’t override or break this on our side.

Since your direct Bedrock calls work but calls through Cursor return “mode ‘default’”, the two are almost certainly resolving to different retention scopes. A few things to check:

  1. Region: put-account-data-retention is a regional setting. Make sure you’ve opted in for the same region you have configured in Cursor’s Bedrock settings. If you’re using the global.anthropic.claude-fable-5 profile, try the us. profile pinned to the region where you enabled it.
  2. Scope: if you set it at the project level (via a Bedrock API key project), note that Cursor authenticates with your IAM access key/secret at account scope. Set it account-wide: aws bedrock put-account-data-retention --mode provider_data_share --region <your Cursor region>
  3. Same credentials: verify with the exact key pair you’ve entered in Cursor: aws bedrock get-account-data-retention --region <your Cursor region> should return provider_data_share.

If all three check out and you still see the error, reply with a fresh request ID from Cursor and we’ll dig into the specific request.

Confirming that did the trick. Thanks!
