Permission Problems

Hey guys,

i am developing an addon at the moment and everytime i try tu run it i get a permission error:

2020-12-02 16:23:28,672 - webServer.server - INFO - start hue entertainment
Exception happened during processing of request from ('', 58181)
Traceback (most recent call last):

    raise child_exception_type(errno_num, err_msg, err_filename)
PermissionError: [Errno 13] Permission denied: '/diyhue/entertain-srv'

I already have chmod a+rwx in my Dockerfile.

Any ideas how to fix this?
