Anyone familiar with that kind of issue :

ApolloError.js:34 Uncaught (in promise) Error: GraphQL error: Cannot query field 'authenticateUser' on type 'Mutation'. Did you mean 'updateUser' or 'createUser'

? It seems that my resolvers aren't caught up by my app (but work in playground)

looks like a mix of project ids

Indeed... Thank you Nilan once again
