I get this error when trying to connect to a graphcool relay API from a react app: Module build failed: Error: No valid GraphQL endpoint

Question

I am following a tutorial from Lynda.com 'Deploying a fullstack react application'. I am using the 'create-react-app project to scaffold my project. For some unknown reason, my app can't access the api, which I can access directly without any issues on the browser. Here's my package.json file, I get the error whenever I run 'yarn start'.

Answer 1

How did you create the service in the first place?

It looks like you might have created it locally only.

https://api.graph.cool/relay/v1/cjazdk3jg0yj70197193cltrf indeed is no valid GraphQL endpoint, it does not exist.

Edit:

Update these two lines

"start": "set GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cjazdk3jg0yj70197193cltrf && node scripts/start.js",
"build": "set GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cjazdk3jg0yj70197193cltrf && node scripts/build.js",

to

"start": "set GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cjb223en111od0191dzu1vba4 && node scripts/start.js",
"build": "set GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cjb223en111od0191dzu1vba4 && node scripts/build.js",

When you deleted the project cjazdk3jg0yj70197193cltrf, the endpoint got removed as well.

Answer 2

Update these two lines:

"start": "set GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cjazdk3jg0yj70197193cltrf && node scripts/start.js",
"build": "set GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cjazdk3jg0yj70197193cltrf && node scripts/build.js",

with these two lines:

"start": "set GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cjazdk3jg0yj70197193cltrf&&node scripts/start.js",
"build": "set GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cjazdk3jg0yj70197193cltrf&&node scripts/build.js",

There should be no spaces between and around &&. Do mark it as correct answer if this solves your question
