Receiving a compilation error when running:
MIX_ENV=prod mix do deps.get, compile, release --env=prod

Full error is:
`== Compilation error in file lib/software/model/file.ex ==
** (CompileError) lib/software/model/file.ex:220: cannot verify size of binary expression in match. If you are concatenating two binaries or nesting a binary inside a bitstring, you need to make sure the size of all fieds in the binary expression are known. The following examples are invalid:

"foo" <> <<field, rest::bits>>
<<"foo", <<field, rest::bitstring>>::binary>>

They are invalid because there is a bits/bitstring component of unknown size given as argument. Those examples could be fixed as:

"foo" <> <<field, rest::binary>>
<<"foo", <<field, rest::bitstring>>::bitstring>>

Got: <path::bitstring()-size(path_size)> :: binary()
