So the error that is popping up appears to be outside anything we are doing:

Exception occurred:
  File "/opt/hostedtoolcache/Python/3.10.15/x64/lib/python3.10/site-packages/tomli/_parser.py", line 716, in parse_value
    return parse_inline_table(src, pos, parse_float, nest_lvl + 1)
TypeError: TomlDecoder.loads.<locals>._parse_inline_table() takes 3 positional arguments but 4 were given
