I am getting the below error when submitting a modern form with a modern text input control that contains more than 255 characters. Changing the text input control from single line to multiline does not change this limit. Is there an option to increase the character limit?
Hi @TrainGuy
The number of characters is the limit of the field you have created.
Where did you do it in Sharepoint or Dataverse, normally in Dataverse it is 255 then you can change it.
Thank you for your response. The text input control is connected to a SharePoint list hyperlink column. It appears that hyperlink columns have a 255 character limit (which is odd considering I was testing this with a SharePoint library link, many of which are longer than 255 characters). Anyway, looks like this is not a Power Apps issue.
Whether it is more associated with the origin and type of data than limitation of power apps.
