Disturbing URL in exception

help
1

Hi,

I got this exception in my project (not yet in production) but there is a URL in there that disturbs me:
http://testp5.mielno.lubin.pl/testproxy.php

Here is the full exception:

Error: url must be a relative URL: http://testp5.mielno.lubin.pl/testproxy.php

Is this a known thing? Searching for that URL doesn’t give me very reassuring results…
