RTK Query "merge-patch+json" content type ruins request body

I am using RTK Query mutation to update my entities. There is api-platform on the backend that accepts only "application/merge-patch+json" Content-Type with PATCH requests. If I try to put this in my mutation's return statement:

method: 'PATCH',
headers: {
  "Content-Type": 'application/merge-patch+json'
},

I get only [object Object] in my request body instead of json. However, if i change my method to "PUT" or Content-Type to "application/json", my request body is as expected and contains valid json.

api-platform.com rtk-query javascript

fetchBaseQuery does not know that content-type by default. In that case instead of passing

  body: something

from your query, you need to pass

  body: JSON.stringify(something)
