I use async_send method, and return the error below. Look like missing some args in response, maybe return more readable error message?

    I have the same issue. I use SDK (chat completion) to generate images using Seedream 4.5 model. If provider returns 400 (and, probably, other 4XX) error (for example, if sensitive content detected), I get ResponseValidationError exception raised:

    Response validation failed: 4 validation errors for Unmarshaller

    Here is the result of e.body.lstrip():

    {"error":{"message":"Provider returned error","code":400,"metadata":{"raw":"{\"error\":{\"code\":\"OutputImageSensitiveContentDetected\",\"message\":\"The request failed because the output image may contain sensitive information...\",\"param\":\"\",\"type\":\"\"}}","provider_name":"Seed","is_byok":false}},"user_id":"user_...giDX9mRqO0uhNo5qPCbXYj"}

    Seems like SDK tries to parse this response as success response, not as error.
