[AsyncRetriever] - Partition router is not working when using the AsyncRetriever

### Topic

The request parameters defined in the partition router are not being sent in creation_requester

### Relevant information

I've started using the AsyncRetriever to create a low code connector in order to integrate a data source.

I have 2 inputs in my configuration file and I'm also using the incremental sync + start_time_option to insert a date as parameter, none of the these variables are being sent to my first request.

Although, when I hard code this parameters in my base request the connector works, the ideal scenario is to use the partitions.

This is my retriever code:

```yaml
