Execute Evaluation flow not working from thursday to friday

[GuetarniTarik]

Hello,

I launched several pipelines on thursday and manage to get the execute evaluation flow working perfectly fine but since friday it doesn't work anymore without any changes to the code. The error is this one :

First error message is: The input for batch run is incorrect. Couldn't find these mapping relations: ${run.outputs.answer}. Please make sure your input mapping keys and values match your YAML input section and input data. For more information, refer to the following documentation: https://aka.ms/pf/column-mapping

I've done all my tests on chat_with_pdf case
