Unable to use "request" library with headers - node.js

Question

Using Chrome dev tools I can see all the requests made. I want to replicate one of them using a script. The request is replicable as replaying it from dev tools works. I'm using this code:
let request = require("request");
request.put("<hidden>", {
"headers": {
":authority": "<hidden>",
":method": "PUT",
":path": "/api/<hidden>",
":scheme": "https",
"accept": "*/*",
"accept-encoding": "gzip, deflate, br",
"accept-language": "en-US",
"authorization": "<hidden>",
"content-length": "0",
// and more
}
}, (err, response, body) => {
console.log(err);
console.log(response.statusCode);
console.log(body);
});
The console says:
TypeError [ERR_INVALID_HTTP_TOKEN]: Header name must be a valid HTTP token [":authority"]
at ClientRequest.setHeader (_http_outgoing.js:487:3)
at new ClientRequest (_http_client.js:221:14)
at Object.request (https.js:309:10)
at Object.request (C:\Users\Admin\AppData\Roaming\npm\node_modules\puppeteer-core\node_modules\agent-base\patch-core.js:25:22)
at Request.start (C:\Users\Admin\AppData\Roaming\npm\node_modules\request\request.js:751:32)
at Request.end (C:\Users\Admin\AppData\Roaming\npm\node_modules\request\request.js:1505:10)
at end (C:\Users\Admin\AppData\Roaming\npm\node_modules\request\request.js:564:14)
at Immediate._onImmediate (C:\Users\Admin\AppData\Roaming\npm\node_modules\request\request.js:578:7)
at processImmediate (internal/timers.js:439:21) {
code: 'ERR_INVALID_HTTP_TOKEN'
}
I tried not using .put(), or specifying method and body properties. Same results.

Headers that show with a leading colon are "pseudo-headers". You don't actually send them yourself with the request() library as they are an illegal http 1.1 header format.
You can read about them here: Purpose of pseudo colon-header fields.
You should be able to remove all the pseudo-headers and just make sure that the information in them is properly specified elsewhere in your request (url, method, etc...) which they would normally already be.
