Relay compiler throws syntax error: unexpected “$” when running in Github Action about get-graphql-schema HOT 3 OPEN

I have managed to find that when running the get-graphql-schema in Github Actions it is adding the script as the first line of the file. I can remove this via an additional script, but unsure why it is being added?

Resulting schema.graphql

$ /home/runner/work/<company-name>/<app-name>/node_modules/.bin/relay-compiler --schema schema.graphql --src src
schema {
  query: query_root
  mutation: mutation_root
  subscription: subscription_root
}
...

This doesn't occur locally instead, I get the following (as expected).

schema {
  query: query_root
  mutation: mutation_root
  subscription: subscription_root
}
...

from get-graphql-schema.

Hi there! Could you explain how you managed to delete that first line that broke everything, please?. Have the same issue.

from get-graphql-schema.

There is a cleaner way to remove the "first line that breaks everything". When you run yarn run X, yarn wraps the output of your script with a header and a footer - the header is what breaks your script.

There's a silent flag you can add that fixes this issue:

scripts: {
  "print-schema": "yarn -s get-graphql-schema http://localhost:3000/graphql > ./data/schema.graphql",
}

From Yarn docs:

-s, --silent skip Yarn console logs, other types of logs (script output) will be printed
