A warning will appear for custom connectors that are missing a unique redirect url:
"The following connectors use a redirect URL shared by other connectors. To address a security vulnerability, update to a unique Redirect URL in their security tab: .. "
Under the security section this checkbox is now available:
However, when updating the security section with this checkbox and saving i get a successful notification:
"Custom connector has been updated successfully. Update the OAuth App registration to include the newly generated redirect URL."
However the redirect url field is still empty, but the checkbox is now gone:
I can assume the end of the redirect uri could can be found by looking at the url for the UI editor, but I don't like to assume things like that. I have also tried downloading with 'pac connector download', but it is also missing the "redirectUrl" property under oAuthSettings in the apiProperties.json file.
Anyone got a reliable workaround or know if this is a known issue?
