Malformed Input Request

I was able to test Stable Image Ultra, core, and sd3 and all return errors like this:

An error occurred
The following error occurred while processing your request:

Error invoking model response: Error executing "InvokeModel" on "https://bedrock-runtime.us-west-2.amazonaws.com/model/stability.stable-i..."; AWS HTTP error: Client error: `POST https://bedrock-runtime.us-west-2.amazonaws.com/model/stability.stable-i...` resulted in a `400 Bad Request` response: {"message":"Malformed input request, please reformat your input and try again."} ValidationException (client): Malformed input request, please reformat your input and try again. - {"message":"Malformed input request, please reformat your input and try again."}

Of the following exception type:

Drupal\ai\Exception\AiRequestErrorException

While I cannot offer assistance coding the repair, I would be happy to provide some testing for a repair! Please let me know how I can assist with this project.

I am elevating this to major because all image models for Amazon titan are not working, and this affects the site functionality I am currently working on

I have tried the current recommended versions of this module and other AI modules with no improvement. I cannot offer coding or API assistance, but I would be happy to contribute with testing and/or site usage for this and other AI modules.

I greatly appreciate any assistance resolving this and bringing the image models to full functionality!
