I have a problem for which routing as it is described in the langchain documentation.

I am restricted to AWS and Bedrock cannot use the ChatOpenAI class and instead have to procceed with ChatBedrock.
According to this overview the with_structured_output method, which I need, is not (yet) implemented for models on AWS Bedrock. I am looking for a workaround or any method to replicate this functionality.

Did anyone find a workaround how to resolve this issue?
