filter_query array brackets get encoded

[coltmans]

Describe the issue you're facing

Hey, we are using your version 3.0.15 at the moment.
I want to filter stories by a date field endtime in a block. Following you docs I should be able to filter, but I get no stories at all.

We are using the .get() method of the getStoryblokApi from you react sdk.
What I see in the network tab, the request url has encoded array brackets for the filter_query: &filter_query%5Benddate%5D%5Bgt_date%5D=2025-05-05%2015%3A41

Changing the request url with non encoded brackets, it's working. &filter_query[enddate][lt_date]=2025-05-05%2015%3A41

That's basically the code:

const response: ISbStories = await getStoryblokApi().get(`cdn/stories/`, {
      ...sbParams,
      content_type: contentType,
      starts_with: country,
      sort_by: 'published_at:desc',
      filter_query: {
        enddate: { lt_date: `${year}-${month}-${day} ${hours}:${minutes}` },
      },
    });
