Somewhere a long the line you have a mis-assigned variable. Looks like your trying to update a column or set a varibale that is a Double with a string.  I have seen this happen if your SharePoint column in currency and your trying to update or create an item with the wrong data type. Does this sound familair to something that could be going on?

I am not updating any column as per my workflow design . error is occuring once flexi task is assigned and requested user update the request and then it throws an error.

Hi!

 

Are you surethis is related to the flexi task action itself? Have you tried adding "Log to history" actions before and after the action, so that you are sure the task is completed and one of its branch picked up?

 

I understand this error as below.

 

First, the reason:

It says, that workflow the input Nintex is trying to process is in other format than expected. Now reading further:

The error is related to the variable, that is used and evaluated as a numeric one. I suspect it should be a number, but is a string or in incorrect format. Now further:

I think that after the Task action you have a Conditional Step that you are trying to check against the outcome of the approval and this is where your workflow fails.

Nevertheless I suggest to put "log to history" actions around the task action. Check outcomes etc... If this doesn't work and you are sure this is task that is a problem, try to remove the old action and create it again, from a scratch.

Thanks for you incite on this . i will try adding log around the flexi task

 

One more thing i found which reassigning task of currently running workflow in sharepoint task list workflow was getting suspended with same error.

I am receieving the same error when task got escalated to a person. All Tasks got escalated succesfuly to that person but the workflow got supsended. I am using "Start a Task Process".
