Issue calling aws bedrock model from playground

[Songnianz]

when I call my aws bedrock model from playground using the model id in langchain's dropdown list, it throws validation error and tells me to retry with correct model ID:

then I found the correct inference profile in aws all starts with "us.":

So I pasted the model ID, but it throws a new error: "ValueError: too many values to unpack (expected 2)":

My guess is langchain couldn't parse the extra dot in model ID. Can anyone fix it?
