I'm assisting with a problem in a project where exporting data to Excel from Umbraco Forms has suddenly stopped working. This feature has been functioning well for 2 years. The issue seems to be with the GetExport method, which downloads exported Excel files from a specific folder in the browser. Recently, users are encountering an error when attempting this.
I discovered that the problem might be related to the browser version, specifically Chrome or Chromium-based browsers. Updating to the latest Chrome version resolved the issue for me and a colleague.
We need to figure out the cause of this issue and find a solution, even though advising clients to update their browser is a temporary fix.
We're using Umbraco 8.18.5 and Umbraco Forms 8.7.6.
