Error with fetch called from npm module

I am trying to use the tsdav NPM package with Deno, and have run into a problem with making an HTTP request, which seems specific to Deno.

When I try to call any request method from the library, I get an error with HttpsClientRequest somewhere deep within some compatibility layer:
error: TypeError: Cannot read properties of undefined (reading 'write')
    at HttpsClientRequest._writeRaw (ext:deno_node/_http_outgoing.ts:422:24)
    at HttpsClientRequest._send (ext:deno_node/_http_outgoing.ts:408:17)
    at HttpsClientRequest.write_ (ext:deno_node/_http_outgoing.ts:316:16)

- Implementation of fetch that gets called by them: https://www.npmjs.com/package/node-fetch

I've only used Deno for a few weeks but I really like it so far, thanks in advance for any help or pointers to relevant docs 😊

I couldn't even find the _http_outgoing.ts in my local deno folder on my own...
