Apollo Client - [POST http://localhost:3000/[object%20Object] 404 (Not Found)]

Hey folks, I’m new to Apollo Client 3.5.10 and I’m having difficulties with client https://api.graphql.jobs/

Getting when running inside Reactjs

Uncaught (in promise) Error: Unexpected token < in JSON at position 0
    at new ApolloError (index.ts:58:1)
    at Object.error (QueryManager.ts:310:1)
    at notifySubscription (module.js:137:1)
    at onNotify (module.js:176:1)
    at SubscriptionObserver.error (module.js:229:1)
    at Object.error (asyncMap.ts:48:1)

    at onNotify (module.js:176:1)

    at iteration.ts:13:1

Here is My Mutation

import {gql} from '@apollo/client';
export const CREATE_JOB_MUTATION = gql`
    mutation postJob(
        $title: String!,
        $commitmentId: ID!,
        $companyName: String!,
        $locationNames: String!,
        $userEmail: String!,
        $description: String!,
        $applyUrl: String!
    ){
        postJob(
            title: $title,
            commitmentId: $commitmentId,
            companyName: $companyName,
            locationNames: $locationNames,
            userEmail: $userEmail,
            description: $description,
            applyUrl: $applyUrl
        ){
            id
        }
    }
`;

Query Variable

mutation{
  postJob(input:{
           title: "Title Goes here...",
            commitmentId: "id...",
            companyName: "companyName.....",
            locationNames: "locationNames....",
            userEmail: "test@test.com",
            description: "description",
            applyUrl: "test.com"
  	}){
    	id
		}
}

https://api.graphql.jobs/

Works fine when I run this on POSTMAN but getting error when try to run inside react

Query on Reactjs Side

    const postNewJob = async () => {
        console.log("Posting New Job");
        await postJob({
            variables: {
                  input:{
                    title,
                    commitmentId: id,
                    companyName: name,
                    locationNames: location,
                    userEmail: email,
                    description,
                    applyUrl: 'https://www.google.com'
                }
            }
});

In the Dev-Tool I get this in the network tab

operationName: "postJob", variables: {},…}
operationName: "postJob"
query: "mutation postJob($title: String!, $commitmentId: ID!, $companyName: String!, $locationNames: String!, $userEmail: String!, $description: String!, $applyUrl: String!) {\n  postJob(\n    title: $title\n    commitmentId: $commitmentId\n    companyName: $companyName\n    locationNames: $locationNames\n    userEmail: $userEmail\n    description: $description\n    applyUrl: $applyUrl\n  ) {\n    id\n    __typename\n  }\n}"
variables: {}

Thanks In Advance
