Pydantic FoldingRangeParams query field ValidationError

[hlouzada]

There seems to be an error with FoldingRangeParams as it's missing the query field. Although it's not specified by LSP and it might be unneeded. As the new release now uses pydantic (#151) it is requiring the query filed and throwing an error if not used.

As specified by LSP:

export interface FoldingRangeParams extends WorkDoneProgressParams,
	PartialResultParams {
	/**
	 * The text document.
	 */
	textDocument: TextDocumentIdentifier;
}

See LSP Reference for more details.

Error Traceback:

Traceback (most recent call last):

  field required (type=value_error.missing)

A possible solution is to remove the query from the FoldingRangeParams implementation:

pygls/pygls/lsp/types/language_features/folding_range.py

Lines 52 to 55 in 6ce5a50

	class FoldingRangeParams(WorkDoneProgressParams, PartialResultParams):
	query: str
	text_document: TextDocumentIdentifier
