I was really surprised that we couldn't just use the path from the args here.
I added a bit of logging to understand things more, and saw it doesn't contain any of the field names.
For this query visiting field name:
query {
data {
items {
name
}
}
}
Built-in path:
['definitions', 0, 'selectionSet', 'selections', 0, 'selectionSet', 'selections', 0, 'selectionSet', 'selections', 0]
→ AST structure path (technical)
pathFromAncestors(ancestors):
['data', 'items', 'name']
→ GraphQL field path (semantic, useful for error messages)

Add path to the fixture input validation error so it is easier to identify where the error is occurring.
