We have upgraded our Dynamics 365 to 2020 wave 1 and now our workflow for email to case has failed. So we used the new automatic record creation that uses power automate to create the rule for creating a case. However, when we now receive emails to our support email the create primary entity part fails with error.
This seems to be because the flow uses the sender email to work out the contact and the account for that contact. It initializes customer variable from the sender email.

Then it works out to set parent of sender as customer
if(empty(outputs('Retrieve_sender_contact')?['body/_parentcustomerid_value']),outputs('Retrieve_sender_contact')?['body/@odata.id'],concat('contacts(',outputs('Retrieve_sender_contact')?['body/_parentcustomerid_value'], ')'))
Then it should place the result in here however it fails.

Any help would be appreciated.
