Function clause error when logging union query

[ding-an-sich]

** (FunctionClauseError) no function clause matching in String.split/3

 The following arguments were given to String.split/3:
 
     # 1
     {:error, "pg_format exited with status code 65280\nUncaught exception: Use of uninitialized value in pattern match (m//) at (...)/deps/ecto_dbg/priv/lib/pgFormatter/Beautify.pm line 965, <STDIN> line 1.\n at (...)/_build/test/lib/ecto_dbg/priv/pg_format line 19, <STDIN> line 1.\n\tmain::__ANON__(\"Use of uninitialized value in pattern match (m//) at (...) called at (...)/deps/ecto_dbg/priv/lib/pgFormatter/Beautify.pm line 965\n\tpgFormatter::Beautify::beautify(pgFormatter::Beautify=HASH(0x56106f996638)) called at (...)/deps/ecto_dbg/priv/lib/pgFormatter/CLI.pm line 170\n\tpgFormatter::CLI::beautify(pgFormatter::CLI=HASH(0x56106f748548)) called at (...)/deps/ecto_dbg/priv/lib/pgFormatter/CLI.pm line 78\n\tpgFormatter::CLI::run(pgFormatter::CLI=HASH(0x56106f748548)) called at (...)/_build/test/lib/ecto_dbg/priv/pg_format line 49"}
 
     # 2
     "\n"
 
     # 3
     []

The error occurs when I'm trying to log a query with multiple union_all. Not sure what's going on.
