Hello Neha,
can you please give us a screenshot of what is the Console prompting?
Hi Neha,
I think this is the same issue occurred in other post. Please refer answer from there

Answer:
There are 3 possibilities for this issue.
1) Access Rules for entity
2) Empty Object at the time of save
3) Microflow permission
Kindly check these point.
Additionally if you are using any java action, then add error handler on it.
Thanks
