The section of the Data 360 Help documentation Install the Query Workspaces Package lists all steps required to setup and use the Query Workspace AppExchange package. When attempting to complete the steps in Create a Named Credential for Query Workspaces you may be redirected to a page with the following error message after completing the steps and clicking Save.
error=redirect_uri_mismatch&error_description=redirect_uri%20must%20match%20configurationThis error indicates an issue with a URL entered during setup is incorrect. Confirm that the URL field when creating the named credential is in the following format, with your org's domain entered in place of [your domain]:
https://[your domain].my.salesforce.com/
If your named credential has the correct URL format, then review the connected app you created when following Create a Connected App for Query Workspaces and doublecheck that the Callback URL also has the same domain format. It should look as follows:
https://[your domain].my.salesforce.com/services/authcallback/QueryWorkspaces
If you copied and pasted your org's domain from the browser address bar, then you may have entered the domain as [your name].lightning.force.com, which can lead to the error during named credential creation. If you need to modify the Callback URL of your connected app, allow 5-10 minutes after saving your changes before re-attempting to create the named credential.
