Hello,

We have two major issues with query forwarding while using the Orion CB

1. Orion is not forwarding the pagination parameters (limit, offset) when
they are used. In addition, when reviewed the log of our Context Provider
we have verified that the request of entities are being requested one to
one from Orion.

Also, after executing a query with pagination parameters, it turns all the
entities without paignation, and returns the following error at the end,
with code 200!!:

Issue: https://github.com/telefonicaid/fiware-orion/issues/847

"errorCode": {

        "code": "200",

        "reasonPhrase": "OK",

        "details": "Count: 0"

    }

We wonder if we are missing some parameter in the registration of the
provider to Orion, we are aware of some limitation using the NGSIv2 so we
have enabled the integration by using the NGSI v1 legacy mode between Orion
and our Custom Provider. ¿any idea fix the pagination forwarding issue?

 2. Similar issue has been found with query filtering, that are not
forwarded to the provider. Actually, it seems Orion doesn't send the filter
in the POST /v1/queryContext to provider. An issue corresponding to this
limitation has been created but not resolved yet
https://github.com/telefonicaid/fiware-orion/issues/2282.

¿Is there any advance in the support of these functionalities or workaround
to address it nowadays?

Thanks in advance

Regards
Ailema
