Can't fetch schema in packaged app, works in dev mode
See original GitHub issueDescribe the bug Sometime last year prior to October, Insomnia (binary) was no longer able to fetch the schema from a graphql server that it previously worked fine with.
The GraphQLEditor component shows a small modal saying Failed to fetch schema: list.reduce is not a function
At the same time though, the schema is resolved without issue in the GraphQL playground provided by the server, the Altair GraphQL app (though they’re using a “GraphQL Event Stream protocol” for schema fetching, I thought it worth mentioning), and I can run the introspection query manually in Insomnia and get a valid response:

__schema {

query type {
__type(name: "List") {

The real notable thing is that this issue is not present when running the app in dev mode.
While running npm run app-start:

The issue was with my plugin, and the plugin has been patched. Thanks for @develohpanda’s help in Slack (thread)
my colleague stumbled upon this bug and realized it doesn’t happen when the plugin I created is disabled!
I think I just need to not have the plugin do anything on introspection requests, but I’m not sure how to check for that in the response context 🤔
