Error " is not a function" working with Column Values with Make/Integromat

I’m trying to create an item on a Monday board using Make (previously Integromat) and get the error:

Data is INVALID because of the error: [Function ‘stringifyColumnValues’ finished with error! is not a function]].

The Monday item does not then get created. I’m not sure which column/value/label is causing this error and warning - is there a way to find out? Any support or guidance is greatly appreciated!

You probably want to take this up with Make support as they can look at the flows and logs directly… what I have done in the past, is to break it down - ie remove have the columns and run the make process, if it works, the issue is in the columns you took out. repeat taking out or adding in half the columns each time until you pinpoint the error.
