Twitter App authentication error


I am getting the following error when configuring Twitter app settings on a new installation. As a result any schedules fail to trigger.

I've added the client's URL to the Callback URL whitelist in Twitter App's settings.

There was an error: Callback URL not approved for this client application. Approved callback URLs can be adjusted in your application settings

I've noticed that Twitter has the following in their docs:

If you do receive this error message, please check the URL that you are using with the callback_url parameter in your oauth/request_token call and make sure that this URL has been whitelisted in your Twitter app settings.

I wonder if the request from Perch is not including this newly-required callback URL in the parameter when trying to auth with Twitter?

Thanks in advance,

Update and temporary fix:

I found that hardcoding the actual callback url set in Twitter app settings and using that as a replacement for tmhUtilities::php_self() in the app, means that Twitter allows the app to authenticate with the API. So something isn't right with the URL that the tmh function utility is generating:

So echoing out the URL into the settings page I get https://DOMAIN/perch/addons/apps/perch_twitter/settings/.

But the site is setup to default to www prefix so the tmh utility function is stripping the www off the URL for some reason.

If I now add this specific URL to the Callback URL in Twitter it all works again. If I don't enter the full URL then the callback function fails once again.

Hi I can confirm this is a bug, you have to add /[YOUR PERCH FOLDER NAME]/addons/apps/perch_twitter/settings/ to your callback URL on the Twitter App Settings to fix as you suggest
