When an experience is configured with a feature layer or table as a data source and no webmap is used within the experience REST JS authorization oath callback fails with a 404 error.

Solution de contournement

Allow longer URLs in the web config. Simply add everything in the <security> tag to increase the allowed query string and URL size.

<?xml version="1.0" encoding="utf-8"?>

<configuration>

 <system.webServer>

  <security>

   <requestFiltering>

    <!-- raise these values to accommodate your long OAuth callback URLs -->

    <requestLimits maxQueryString="8192" maxUrl="8192" />

   </requestFiltering>

  </security>

 </system.webServer>

</configuration>
