Value cannot be null. (Parameter 'key')

AppSheet AppSheet Q&A

Hi,

I am experiencing the issue " Value cannot be null. (Parameter ‘key’)" in my app.

It occurred after having done few changes but then discarded them.

The colum "Key"in the file is filled.

How can I fix this issue? What should I check?

Thank you

Is this an AppSheet problem? If so, please post a screenshot showing the error and a screenshot of the column’s configuration.

Hello,

I am experiencing the same issue as the original poster, where the error message “Value cannot be null. (Parameter ‘key’)” appears each time I perform ‘Regenerate Schema,’ but it disappears after saving.

Here’s a screenshot of the error message:

Interestingly, this issue started on the same day the original post was made. I have already checked all the key columns in the database, and they appear to be properly filled.

Since I have too many columns to send a configuration for each, could you kindly provide some guidance on what steps I should take to resolve this issue?

Thank you very much for your assistance!
