Hi snehal!
Which entity are you using? Because the error is due to security reasons. Can you check if you have permissions to write that attribute on your entity access tab. It is inside the security of the module.
Kind Regards,
Emilio
Hey Snehal!
I have done some tests just to check if the nanoflow causes some problems and everything works fine, the nanoflow cleans the field when I enter in the page.
Can you turn off the security of the application and test if the application works as you want? That will give us some clues of what is causing this issue
