Fix the trigger – Microsoft.OData.ODataException: A binary operator with incompatible types was detected. Found operand types ‘Edm.Guid’ and ‘Edm.String’ for operator kind ‘Equal’ (Power Automate / Dataverse)

Recently in one of our flow triggers – When a row is modified (Dataverse), we got the below error

Exception parsing _msdyn_billingaccount_value eq ‘a84c5028-ecdf-ed11-a7c7-00224893b2b0’ submitted for attribute filterexpression of callback registration. Target entity: msdyn_workorder. Exception: Microsoft.OData.ODataException: A binary operator with incompatible types was detected. Found operand types ‘Edm.Guid’ and ‘Edm.String’ for operator kind ‘Equal’.

This is because we were using single quotes around the GUID value in the Filter rows property.

We need to remove the single quotes around the GUID

GUIDs are considered a primitive data type in OData and should be represented as raw values without quotes. By removing the single quotes, we’ll ensure that the GUID is treated as a valid identifier in our filter condition.

Hope it helps..
