无法在中继编译器中为突变生成自动生成的文件

Question

I am trying to create a web application with ReactJs as frontend, GraphQL as service layer and Relay as communication between service layer and frontend.

In this i created a mutation in service layer and integrated in front end.At last tried to generate files using following commands

1. relay-compiler --src ./src --schema ./schema.graphql

2. get-graphql-schema http://localhost:6001/xampr > schema.graphql

None of these are working by throwing this errors

• Writing js

  ERROR:
  You supplied a GraphQL document with validation errors:Unknown type "GetActivityMessagesRequestInput". Services/Auth/GetActivityMessagesMutation.js (2:49) 1: 2: mutation GetActivityMessagesMutation($input:GetActivityMessagesRequestInput!) { ^3: getActivityMessagesRequest(input : $input){ error Command failed with exit code 100.

• GraphQL is not found

• Stack is empty unable to convert undefined to graphQL query

My relay script tag is

"relay": "relay-compiler --src ./src --schema ./schema.graphql --watchman false"

Tried to uninstall an reinstall all packages

"relay": "relay-compiler --src ./src --schema ./schema.graphql --watchman false"

Unable to create generated mutation files using relay compiler

According to the error message, GetActivityMessagesRequestInput isn't a valid graphQL input defined in your schema.

Check your server schema for that input definition if it exists, else see what the right input to pass to that mutation is. You might as well call the scalar input directly.

It might be GetActivityMessagesCreateInput .

Example to demonstrate what I mean.

signin(email: String!, password: String!): AuthPayload! updateProfile(data: UserUpdateInput!, id: ID): User!

If I call sign mutation like so

mutation SignIn ($input: SignInMutationInput!) { signin(input: $input){ user: { id, email } token }

It will return the same error as yours saying You supplied a GraphQL document with validation errors:Unknown type "SignInMutationInput"

To fix the above, I can either create a custom input type in my server called input SignInMutationInput { email: String! password: String! } input SignInMutationInput { email: String! password: String! } input SignInMutationInput { email: String! password: String! } OR change the way I'm calling the mutation like so;

mutation SignIn ($email: String!, $password: String! ) { signin(email: $email, password: $password){ user: { id, email } token }

I hope this helps.
