Hello,
I use Chartmueseum with a dynamic depth. When I looked in the logs, I noticed some panic messages when I try to call Chartmuseum URL by browser.
So I enabled the debug output I noticed the problem:

It looks like my Chrome Browser is trying to get a favicon, which of course doesn't work. Unfortunately this call causes a panic message. When I do a curl on the api (withot favicon ;)) I don't have this problem.
I tested also some other urls with the same behavior, like:
