UpdateIf Formula Returning Error

I migrated an app from one environment to another.

I have two buttons in the app, a Submit (new), and a Submit (edit).

I am getting no errors on the Submit (new; It is using Patch) button.

However, the Submit (edit, using UpdateIf) button is kicking back the following error -
Name isn't valid. '{0}' isn't recognized.

The UpdateIf, in the original environment is exactly as shown below, has no such error.

Why is the formula generating this error in the new environment?

Power App Submit (edit) Button OnSelect -

SharePoint Test List -

Hi @Phineas

I suspect that one of the field name/values is incorrect. This might be because the field names in the datasource of your target environment doesn't match the original.

To diagnose this, I'd comment out each line in your UpdateIf statement one by one to help identify the field that's causing this error.

Alternatively, you could also try running a Monitor session to see if that reveals any more details.

I understand the "comment out".

What is a "Monitor" session and how is it initiated?

Hi @Phineas

The link on how to use Monitor is here.

https://learn.microsoft.com/en-us/power-apps/maker/monitor-overview

The useful part is the "Debugging canvas apps with Monitor" section. If you can trace the error, the detail may give you the actual name behind the error "Name isn't valid" which may help you solve this.
