String array in query appends [] to the query variable name

[gunnartorfis]

What are the steps to reproduce this issue?

1. Describe a GET request with query parameter that is an array of strings
2. Inspect Orval client will send the request with name[]=value instead of name=value in the query

What happens?

Request will be with incorrect query param.

What were you expecting to happen?

The query param name shouldn't be appended with [].

What versions are you using?

Operating System: macOS Big Sur 11.6 Package Version: Always latest, running in CI pipeline Browser Version: Safari 15.0

Seems like it's by design: https://github.com/anymaniax/orval/blob/f3b2d4f6cead82a15e1486c03ab1533d5de716ea/src/core/getters/array.ts#L27

May I ask why? The documentation we're using doesn't generate the query param with [], neither does our Golang API server stub generator.

Dealing with the same issue :/

I managed to find a solution using axios' paramsSerializer config field

import qs from "qs"
...
{
    paramsSerializer: (params) =>
          qs.stringify(params, { arrayFormat: "comma", indices: false }),
}

Is there any update on this improvement? I have followed @fr3fou approach so far. Please note that today, paramsSerializer is an object and the function is performed as follows:

paramsSerializer: {
        serialize: (params) => {
            return qs.stringify(...)
        }
      }

Also having the same issue, any updates? Would love to get this fixed as I'm working with over 100 API endpoints and multiple require array parameters.
