Has anyone experienced any odd behaviour with the asset builder recently? We upgraded a couple of weeks ago from 4.16 to 5.1 and on investigating a problem with one of our image upload features I've found the confirmation page returned by the asset builder includes some junk characters and a huge chunk of PHP code prefixing the actual html specified in the "created" bodycopy. I have some JS code that parses the return, which should just include a simple DIV with the asset ID of the created asset, and its failing because of all the junk prefixed on the front. I can work around it, but seems like a bug to me. There is a blank design specified and no paint layout, so should literally be seeing the couple of lines of HTML. Worked fine for years up until we upgraded.
Any thoughts appreciated
