Report services are not working post 22A upgrade

Summary:

REST services related to OTBI are failing in the system which worked fine until the 22A upgrade.

Content (required):

One of them is 'runDataModel' which we use to run the data model existing in the system and extract data.

Response after 22A: 

<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope"><env:Header/><env:Body><env:Fault><env:Code xmlns:env="http://www.w3.org/2003/05/soap-envelope"><env:Value>env:Sender</env:Value></env:Code><env:Reason><env:Text xml:lang="en-US">Unknown method</env:Text></env:Reason></env:Fault></env:Body></env:Envelope>

There are other automation that is failing too related to "PublicReportService" where "login" action is failing with "The given SOAPAction login does not match an operation"
