[BUG] Population breaks when specify array of multiple objects (necessary for nested population)

When using population the module has a bug regarding array of population objects. I have four schemas: games, characters, locations and events. The schema itself does not really matter. When I specify an array of strings for fields to be populated, it works.

WORKING

axios({
      method:'get',
      url: config.apiUri + '/game/' + id,
      params: {
        populate: ['characters', 'events', 'locations'],
      },
    })

If you want to do a nested populate you would need to specify a path. The following example also works (also the nested events field gets populated).

WORKING

axios({
      method:'get',
      url: config.apiUri + '/game/' + id,
      params: {
        populate: [{
          path: 'locations',
          populate: {
            path: 'events'
          },
        }],
      },
    })

However if you specify an array of objects as populate param, the population breaks and all populated fields return a null value. This happens regardless whether you do a nested population or not.

NOT WORKING

axios({
      method:'get',
      url: config.apiUri + '/game/' + id,
      params: {
        populate: [{
          path: 'locations',
          populate: {
            path: 'events'
          },
        }, {
          path: 'characters'
        }],
      },
    })

@Zertz Thank you, didn’t know about this not being standardized. Sorry for making a fuzz,

Passing arrays in query strings isn’t standardized and axios seems to be generating a different format.

What I usually do is build a plain old JavaScript object and then JSON.stringify it into the query string.
