Hi,
I'm having problems with a Flow that is trying to get a list of records from a custom entity in Dynamics 365.
The custom entity [Contact Roles] has a lookup column to the Contact entity and the field is called abs_ContactId.
A Contact can have multiple Contact Roles which is why the Contact lookup is on the Contact Role entity.
So I thought it would simply be a case of:
Get Contact that's being updated
Use the Contacts' Id to get a list of Contact Roles and then update a few fields on the Contact Roles entity.
Like below:

However, I get this message when I try the query above:
"status": 400,
"message": "A binary operator with incompatible types was detected. Found operand types 'Microsoft.Dynamics.CRM.contact' and 'Edm.Guid' for operator kind 'Equal'.",
Am I missing something obvious here? How do I get around this?
