Hi All,
I am getting the below error at the bottom of interface canvas when configuring the GridPlus component. I am on Appian version 25.2.
Error: SyntaxError: Unexpected token '<', "<!DOCTYPE "... is not valid JSON
Use case: An user input grid where user can copy and paste large data set from excel
I have followed the documentation and all the expression rules(queryRuleName, columnConfigs) are working individually. Any guidance will be appreciated.

This is an issue with your browser's third-party cookie settings. If the page connects to an external URL (e.g. an API endpoint, a CDN) and connect-src is not explicitly set, the browser will check default-src. If that's set to 'self' and the external URL doesn't match, the browser will block the connection and display the error.
