Hi Tanay,
Thank you for reaching out to the support tea and for highlighting the error! Let me look into this and escalate to the appropriate team. I'll respond shortly with an update.
Thanks Munnawar H.!
It seems to be working on my end, can you send me a link to the table that you tried this on? And maybe a copy of the document that you're trying to upload if possible?
Hi Munnawar H.! Here you go, click here for the table! Steps to replicate:
Click into the AI column’s config settings (Character Count)
Scroll to the bottom for Document Context (Beta)
Try and upload any PDF or text file here
Does that work for you?
Yes it worked as expected. I uploaded a random PDF and it uploaded and the column was saved. I did not run the row and will remove the PDF now. Do you mind me asking what type of file you tried to upoad?
Munnawar H. strange! Just a random PDF (attaching it here) I just logged out, cleared the cache, logged back in, tried again. Same issue BTW my client faced the same issue - completely different location (Japan)
