説明

This is an output of parcel bundler when running the embedded web server ("parcel ./entrypoint/index.html"). I think this warnings are related to this project and not from parcel itself, but let me know if I'm wrong...

調査方針: The issue reports warnings from Parcel about missing source files in source maps of Apollo packages. To address this, investigate the Parcel configuration and how source maps are generated for the project's dependencies. Check if the warnings are harmless or indicate a real issue. Possible solutions include updating Parcel configuration to ignore these warnings or ensuring that Apollo's source maps are correctly referenced. Look at the project's package.json and Parcel setup for clues.
