So, we made a custom module where you have the option to fill in several options like a text with a CTA, a title,...
One problem: the URL field which should enable us to put a link to a microsoft form behind our CTA, doesn't work for some reason. Every time we click on the CTA, we get a notification with an error code.
There are several causes why a 400 Bad Request error might appear.The majority of them are due to an issue on the client-side of things.
The cause of a 400 error can be a wrongly written URL or a URL that contains unrecognizable characters.
If the URL is correct, then another cause of the error might be an invalid or expired cookie. For example, you can be presented with a 400 Bad Request error when you attempt to log into a site as admin but the cookie that's handling your authentication data is corrupted.
There's also the possibility of the server coming back with a 400 error if you try to upload a file that's too large. If the server is programmed with a file size limit, then you might encounter a 400 error.
In rare cases, the reason why you see a 400 error might be due to specific problems with the server."
So this leads me to question if the URL works when manually pasted into the browser?
And if it does, try going to the link in a private browser to simulate expired, corrupt, or absent cookies.
