How do I fix and Error loading control error?

Last week I noticed that two of my comboboxes started having issues loading as seen in the image below. At first i thought it had to do with the Power Apps release number. I noticed the issues with 3.21054.36. I rolled back to a previous version, 3.21053.21, and everything seemed to be fine. I load up the app today, still on 3.21053.21, and the comboboxes are failing to load again.

A couple things to note about these comboboxes.

  1. They have their own datasources
  2. Each gets refreshed when a value is submitted(patched) to the datasource via a text input

The only thing that has changed recently is that the button for the text input got a bit of an upgrade. When the button clicks it now checks to see if the value is a duplicate and if it finds a duplicate there is an notify message and the background color of the text box changes color. It also sends a Teams message when the new value is added. I fail how to see this is relevant to the combobox.

 

Any ideas what else I should look at to debug this?

    Oh wow. I think I may have found the issue. Somehow I had some blank entries in my datasource. That seems to imply that whatever I am doing with the text input field and button is putting blank entries into the datasource.....I think.

    Yes. I see what is happening. If I click the "Add" button with no value in the text input it enters a blank record. Previously it would not input anything if there was no value in the text input. Looks like a simple change from IsBlank to !IsBlank.

    Would be nice if there was some indication of what was going on. Fortunately I found another post that gave me a clue what the issue was.
