typegen Invalid URL error

[chrber04]

Hi, I've been trying to get typegen to work for a while now but I constantly get this error:

DeprecationWarning: 'createInterfaceDeclaration' has been deprecated since v4.8.0. Decorators are no longer supported for this function. Callers should switch to an overload that does not accept a 'decorators' parameter.
node:internal/errors:491
    ErrorCaptureStackTrace(err);
    ^
TypeError [ERR_INVALID_URL]: Invalid URL
    at new NodeError (node:internal/errors:400:5)
    at URL.onParseError (node:internal/url:565:9)
    at new URL (node:internal/url:645:5)
... more

I installed typegen by running npm

install -g openapi-client-axios-typegen

And I've tried multiple variations of running typegen, with a local file and the remote URL in the README.md documentation. So:

typegen ./openapi.yml typegen ./openapi.yml > client.d.ts typegen https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v3.0/petstore.yaml typegen https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v3.0/petstore.yaml > client.d.ts

They all give me the same exact "[ERR_INVALID_URL]" error. Am I doing something wrong?

Thanks!

Hi @chrber04 these commands all work fine for me with the latest version of typegen.

$ typegen --version
6.1.4
$ typegen https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v3.0/petstore.yaml
# ...
export type Client = OpenAPIClient<OperationMethods, PathsDictionary>

Are you on Windows?

Can you try with npx:

npx openapi-client-axios-typegen https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v3.0/petstore.yaml

Or with specific version

npx openapi-client-axios-typegen@6.1.4 https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v3.0/petstore.yaml

Hello, same here. Tested on node v18 & v16.

Fixed the problem on a fork. https://github.com/adrien-powder/json-schema-ref-parser/commit/494bb14d47873b3245e4379777de29fa522aa81c

The problem still persists for me.

[anttiviljami]

I've replaced SwaggerParser with a much simpler implementation of dereference-json-schema

openapi-client-axios@>=7.0.0 should be much simpler to build for React Native and browser without the need for polyfills. 🙌

[conradkirschner]

I am facing the same problem, was it fixed?

[JoshuaTheMiller]

Hey @anttiviljami! This problem seems to still be occurring, or perhaps it is simply operator error on my part 🤔 Either way it looks like a few folks would appreciate some solution around this still!

Ah. this actually seems to be a problem with the underlying URL class from Node itself... Perhaps not an issue, but rather a misuse of it (I'm still digging into this myself)?

For example, simply running the following snippet on Windows fails:

const to = "./openapi.yaml";
const fromPath = "C:\\";
let resolvedUrl = new URL(to, new URL(fromPath, "resolve://"));  
console.log(resolvedUrl)

[JoshuaTheMiller]

Wrapping the following block of code (which I believe is from this library) "fixed" the problem:

problem still exists. any updates?
