TypeError: Type is not JSON serializable: numpy.float64
This error is thrown on a line in a flow that simply passes 3 dataframes into a function call. Like nothing within the code, it's the line that calls the function. Does anyone know what this is?
Can you give some context?
I believe we’ve resolved this in a later release but I also can’t be sure without more context 🙂
