Got this error when trying to generate typings using the definitionsFactory. UnhandledPromiseRejectionWarning: TypeError: graphql.getDescription is not a function

any ideas?

Thanks

@lukeypap did you solve that issue?

We recently got a similar one after updating GraphQL related packages in a very large project...

Our stack trace is following:

I don't see how it's related to merge-graphql-schemas (more like in our case it's coming from @nestjs\graphql), but we are using @graphql-tools/merge too in our project... so not sure...

UPDATE: issue solved by downgrading graphql package from version 16.0.1 to version 15.7.2 :)

@evereq

The only solution that worked for me too :)
