Deletion commands do not work via fetch

[CraigglesO]

NodeJS version: v16.13.2
Stripe version: ^8.197.0

I am using a cloudflare worker, so if you check the webpack config here you can see it is limiting stripe to fetch and building like so:

const STRIPE = Stripe(STRIPE_API_CODE, { httpClient: Stripe.createFetchHttpClient() })

commands like await STRIPE.customers.deleteTaxId and await STRIPE.customers.del do not work. An example error is as follows:

Zo [Error]: An error occurred with our connection to Stripe.

I believe RequestContentLengthMismatchError is the key to this error.

I'm also running into something similar to this, not for delete requests though. I think the issue is that the stripe lib sets content-length to 0 for empty requests and the fetch implementation by Cloudflare uses undici which doesn't allow that. Not sure if the Cloudflare fetch wrapper is doing something wrong or most other http client implementations choose to fix that for you instead of bombing like undici does, it's a bit silly IMO.

I think this has to be addressed in wrangler or wherever that fetch > undici bridge lives

Seems this has been fixed in miniflare 2.4.0 (not published to npm yet, probably will be soon): cloudflare/miniflare#193

Just incase stripe is ok with this fix:
#1370

Thanks for the detailed report! We've fixed this in #1388 and will be rolling this out as part of the next release. Sorry for the trouble here.
