LangChain Hugging face model for PromptTemplate class

when invoking the Intel/dynamic_tinybert model in the HuggingFaceEndpoint/HuggingFaceHub class in langchain for a translation/Q&A task, one persistent error was as below:

Bad request: Error in inputs: value is not a valid dict

even when passing the input in the prompt as a dict value type, the error was the same.

The HuggingFaceEndpoint/HuggingFaceHub class was used for the langchain example but the repo_id, which was previously google/flan-t5-x1 was replace with Intel/dynamic_tinybert as the former is no longer available.

what is the ideal input format for the model, when using langchain?

Thanks

I have tried other model but the same invalid input error was returned i.e.

Bad request: Error in inputs: value is not a valid dict

eventually, I found that the

mistralai/Mistral-7B-Instruct-v0.2

model could take a string as input prompt that returns a valid response.
