I ran Dialyzer and got the following error:
Checking whether the PLT /tmp/.BRANCH.service.deps.plt is up-to-date...

What went wrong and how do I fix it? What do the list of integers mean?
The print-out inside the dialyzer_error tuple is an iolist. We can pretty print it using the Erlang shell (started with erl):
1> [78,111,116,32,97,32,114,101,103,117,108,97,114,32,102,105,108,101,58,32].

You realize it is complaining about bytecode (.beam) from a previous compiler version than the current one I am running. I removed them, and then it ran.
