Reproduce the error while editing a Swift file in IntelliJ 2025.3.3 with SourceKit-LSP, focusing on the textDocument/declaration request. Start from LanguageServerWrapper.java and the lsp4j RemoteEndpoint stack entries shown in the report, then trace how unsupported methods are consumed. Done means the reported error no longer occurs or declaration handling has a verified expected result.
