Invalid Template

[Anonymous]

Hi there I starting the long journey from a non technical skillset... 'Less code more Power'  Would like to know what this error means?

InvalidTemplate. Unable to process template language expressions for action 'Condition' at line '1' and column '2883': 'The template language function 'greaterOrEquals' expects two parameter of matching types. The function was invoked with values of type 'Null' and 'String' that do not match.'.

It means that you tried to compare something with null, which are different data types and so it didn't work out. You can convert your null value to an empty string. But really it would be easier if you took some screenshots of your flow and then we can help you figure out where it went wrong.

How to take a screenshot of a Flow

Basically what I am trying to do is set up a flow that an email will goto the REVIEWER in the Reviewer column and a PMO address and notify them -30 days before the Review date in the REVIEW DATE column I have set up. Im new to this and after a few hours it gets a bit fuzzy...  I am used to expressions etc in Excel but a long time ago 🙂 Thx
