This means that the plugin will use the internal RSS feed creation, which may not match your use case.
This behavior will be removed in the next major release of gatsby-plugin-feed.

To recap: the problem is that any node mutations (createNode, deleteNode, etc) are now deferred until develop machine reaches the waiting state. But in this example, a custom resolver awaits when node mutation completes. It doesn’t allow the query to finish and transition to waiting state. So it’s a chicken and egg problem.

I don’t have enough context on our state charts yet to fix this correctly. The only idea I have so far is to debounce the runMutationBatch call when we see ADD_NODE_MUTATION in runningQueries state.

I’m closing this because it should be fixed in the latest version. I have tested it with @swkeever 's site and confirmed that it now works.

If anybody is still having the problem with the latest verison of gatsby, please open a new ticket that includes the output from gatsby develop --verbose, with a link to a reproduction. Thanks everyone for the reports!
