[erlang-questions] Cowboy - cowboy_req:reply

Now when I probed what happens during the 500 error, I see the following
error in the Erlang logs.

Ranch listener http had connection process started with
cowboy_protocol:start_link/4 at <0.2399.0> exit with reason:
{cowboy_handler,[{class,error},{reason,{badmatch,{error,enoent}}},{mfa,{cowboy_static,init,2}},{stacktrace,[{filename,absname,1,[{file,"filename.erl"},{line,68}]},{cowboy_static,init_dir,3,[{file,"../src/cowboy_static.erl"},{line,82}]},{cowboy_handler,execute,2,[{file,"../src/cowb

But all the files are present in the server, and their read access rights
have not changed.

Do you have a quick guess?
