Hi,

Could you provide more details on which event do you encounter the error? This usually arises when you pass a value that is of a different data type than what the field is expecting. In that case, you will need to verify the data that is passed in to the event. 

I am passing  values to smartobject to return some values from SQL table. I checked datatype of all parameters and they are same.

Is it possible to do some debugging on workflow or popup message implementaion in workflow to give me more details about error?

Good day 

I recently encountered the same error on my workflow and what I did, I changed the datatypes of my MySQL server to type "VARCHAR 50" and left only my primary_id data type to int and my date variables to remain in the date datatype but where calculated values where in decimal,number or any other numeric type.

Please feel free to ask any further questions if you would like more clarity.
