What causes "Request Rejected: Cannot request existing view on streamId that is not opened"

@jeffwilcox1

Thank you for reaching out to us.

The status message is from ADS. I can replicate this error by using the view request without payload. The RSSL_RQMF_HAS_VIEW is set and the containerType is RSSL_DT_NO_DATA.

Typically, the view request will have an element list in the payload.

The containerType is RSSL_DT_ELEMENT_LIST.

Please check how you encode the view request message.
