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)


The article discusses an error that occurs in the "When a row is modified" trigger in Power Automate (formerly Microsoft Flow) when using the Dataverse connector. The error message states that there is a binary operator with incompatible types, specifically 'Edm.Guid' and 'Edm.String', for the 'Equal' operator. The cause of this error is the use of single quotes around the GUID value in the "Filter rows" property. To fix the error, the single quotes should be removed so that the GUID is treated as a valid identifier in the filter condition.
