PowerApps Forms - Help with Strange Validation Errors

Hello everybody,
I have a strange issue that I've been driving myself crazy to figure out... I'm in the process of building an app for our Marketing department, where end users can submit certain requests from our marketing department. I have the app all built out and started doing some testing on my own before I gave it to the business to test. I came across a very strange validation error that is popping up on just two random fields but no others. Neither of these fields are required from the data source or in the app itself. The other strange thing is they are both text fields but the error message is describing "Value must be between 1 and 1048576" as if it was a number field. Anyone have any ideas as to what could be throwing this error? I am completely out of ideas to try on my end!
Thank you in advance for any help you can provide!


@Anonymous could you unmark this as spam please?  Not sure what I did to get it caught as such. Thanks!

Regarding "Ad Size" and "Editorial Services Description"


  1. In PowerApps which Data Source fields are these two PowerApps fields pointing to?
  2. And for those fields, what are the details?
  3. If the Data Source is Common Data Service or Dynamics 365, Any Business Rules active and if so, what are the details?
    1. Assuming CDS is the data source, if you have a development environment of CDS and development copy of this app hooked to the development environment, try and deactivate all business rules on the development environment and see if the issue persists.
    2. In PowerApps Studio you may need to refresh the data source at design-time by going to Data Sources and clicking the refresh icon.
