Error during Vector Store File generation

I have created an Assistant through Playground and I have attached a json file to File Search (through a Vector Store). When I check the file status by clicking the Vector Store icon the system shows me a “Failed” status under Uploaded Column.

Then I have asked to the assistant what is the content of the json I have uploaded. The attributes and data are different from the ones I have uploaded!!! I think that the assistant was reading another file :frowning:

I have checked out the content of the json I have uploaded but it is completely different from the information the assistant has retrieved from the file.

Has someone encountered this same error or something like that?

Thanks for the support,
Gianluca
