Status for Consent results in 500 when redirect is not finished yet

When Initiate payment is done with
post /v1/banking/pis/payments/{payment-product}
any
get /v1/banking/pis/payments/{payment-product}
to returned handle fails as long as redirect has not finished.

Of course bank may not know payment, as redirect might not be finished yet but tpp does. So it can return status pending or anything similar. If this is regarded as a feature, please let us have a talk.
