Axios has recently done a major upgrade and starting by its version 1.x I am unable to correctly introduce my own parameter serializer to it.

I used to do it as follows:

axios.defaults.paramsSerializer = params => qs.stringify(params, { arrayFormat: 'ma', encode: false });

Now the definition of paramsSerializer is changed to the following:

axios.defaults.paramsSerializer = {
    indexes: null,
    encode: ...
}

Does anyone know how I can assign my serializer to it considering the new definition?
