Request for clearer error message parsing pyproject.toml
Issue Kind
Change in current behaviour
Description
When the tool.poetry.source section in pyproject.toml is provided as a [single table] rather than [[array of tables]] the error poetry provides isn't very helpful:
The Poetry configuration is invalid:
- data.source must be array
A more descriptive error and/or a reference to what section or line in the toml would be a little more friendly. Tried this with -vvv and the stack trace also doesn't give a clue to what part of the toml is actually the problem.
A more broad way to phrase it, if you like, might be "toml structure errors should report a line or section if possible"
Impact
Some more info in the error would make troubleshooting faster; as it is one either 'just knows' the expected structure or goes section by section, which might be slower or faster depending on the size of pyproject.toml.
Workarounds
None that I'm aware of
