I get from the command line a bunch of weird characters such as:

I checked the folder and the map file is there and is readable. I also
tried the same command on a string that has no layers enabled and I get a
clean response. I've copied the same project to localhost environment,
enabled all the same layers and it worked fine. Could this be something
related to the amount of variables passed in the URL ?
