OpenApiClientProvider with Stripe's open API hangs (3MB json)

Description

The autocompletion hangs and stops working when using OpenApiClientProvider with Stripe’s open API. No visible error happens anywhere.

Repro steps

1. Try to use OpenApiClientProvider with the stripe API

open SwaggerProvider

let [<Literal>] Schema = "https://raw.githubusercontent.com/stripe/openapi/master/openapi/spec3.sdk.json"
// __SOURCE_DIRECTORY__ + "/openapi/stripe.spec3.json"
type Stripe = OpenApiClientProvider<Schema>

let main argv =
    let stripe = Stripe.Client()
    // the autocompletion dies or stops working at this point

That JSON file is about 3MB

Expected behaviour

I would expect to work as with any other open API or to get a visible error somewhere

Actual behavior

The autocompletion dies or stops working and doesn’t seem to recover. To wait a large amount of time does not help.

Known workarounds

None:

• All F# IDEs behave in the same way.
• Serving the schema from the localhost doesn’t make any difference.

Related information

• Mac OS (I tried all known F# IDEs)
• Master
• I used the stripe API which is quite popular: https://github.com/stripe/openapi/tree/master/openapi

Nice! But I’ve experienced those issues also with other OpenAPI services (not 3MB though) and it would be nice to have a solution for those performance problems.

I also had issues of slowdown with bigger openapi files, would be great if there could be some perf optimization, or improve caching (or generate some offline schema that could be re-used from file system, once the generation has happened already?) This type provider is awesome 💌
