Cannot download GraphQL schema from endpoint

Question

I'm currently using graphql-cli from Prisma to download the schema from endpoint. But, even after I deploy the changes I made to my schema, which gets deployed successfully, whenever I try to download the schema, I get project prisma - No changes . And the generated prisma.graphql is left unchanged.

I use the following command to download the schema:

graphql get-schema -p prisma --dotenv config/dev.env

dev.env is simply to get PRISMA_ENDPOINT=http://localhost:4466/ environment variable.

I tried to generate prisma.graphql in a different way by having the following in prisma.yml :

endpoint: ${env:PRISMA_ENDPOINT}
datamodel: datamodel.prisma
generate:
   - generator: graphql-schema
     output: ./generated/

And executed prisma generate , but I get the error:

▸ [WARNING] in /Users/F/Documents/d/server/prisma/prisma.yml: A valid environment ▸ variable to satisfy the declaration 'env:PRISMA_ENDPOINT' could not be found.

Tried stopping and recreating Docker as well as deleting the node_module and re-installing, but to no avail.

My package.json :

To fix the error "variable to satisfy the declaration 'env:PRISMA_ENDPOINT' could not be found." when calling prisma generate you should either set the PRISMA_ENDPOINT variable manually or load it via dotenv . For example you could run npx dotenv -- prisma generate to load the env vars from your .env file.

To download the schema from the endpoint via graphql get-schema make sure to provide a properly configured .graphqlconfig.yml and provide the correct project. A sample configuration for a prisma project could look like this:

projects:
  prisma:
    schemaPath: 'src/schema.graphql'
    extensions:
      endpoints:
        default: 'http://localhost:4000/graphql'
  database:
    schemaPath: 'src/generated/prisma.graphql'
    extensions:
      prisma: 'database/prisma.yml'
      endpoints:
        default: 'http://localhost:4466'
