Newline-escape-hell when posting a new schema

What I want to do

POST a new schema to /admin/schema. Everything works if i just include the schema itself, but when i add the # Dgraph.Authorization line, specifically the RSA key for JWT verification, everything breaks.

What I did

As per the docs, newlines in the key have to be written as \n. I tried sending this via nodejs at first (didn’t work because javascript handles newlines differently). Then i changed these newlines to \\n. That didnt work either because the server now complains about the invalid format \\n. Then i tried using curl with the --data-binary flag. I get the same error as when using \\n to escape newlines.

You know how it’s often just really simple errors that make you search the internet for a solution for hours? Turns out this is what happened: I forgot a single comma at the end of the Dgraph.Authorization line. For everyone who came across this I suggest double- and triple‑checking your code for typing errors.
