JWT - Error: null value at left hand side operand in arithmetic multiplication operation.

[Jeff Foege]

I'm using the Jira Workflow Toolbox to create a risk score by using 3 custom fields. I have the Risk Score getting set when it transitions from Create > Open just fine.  Figuring that people might want to alter the Risk Score I setup the same configuration when going from Open > In Progress but I go to submit it I get the following: Error: null value at left hand side operand in arithmetic multiplication operation. Below is the configuration that I have for both transitions; Create > Open and Open > In Progress. 

If the Ephemeral numbers are only used for the transition and I have it set Ephemeral number the second time then the value shouldn't be null.  What am I missing? 

Thanks for any help!

Hello @Jeff Foege

Are you sure that there isn't any mistake in the configuration of transition Open > In Progress? Please, double check your configuration.

It's also possible that when you are transitioning Open > In Progress some of the fields "Risk Severity", "Risk Probability" or "Detectability" are not set.

I recommend you to set a default value in case of one of those fields are not set. To do it you can add an additional setting rule like this one:

(.*)1

For example, for setting Risk Severity you can use:

(Negligible)0.3

(Minor)0.5

(Moderate)1

(High)3

(Critical)5

(.*)1

This way, you are setting Moderate as default value for Risk Severity.

I know its setup correctly cause everything works when going from Create > Open and I used that configuration to setup the Open > In progress transition.  The Risk Score gets set from Create > Open but if I try it again I get that null value error.

When I had those fields being set without doing the math step for the transition from Open > In progress it through an error.

I read something on an old site for this tool about adding [true]0 to the first place of the execution order. I'm just not sure what this means, the math step?

If I can get this working then I would be done.

HAHAHA. You were right I didn't have it configured correctly. When setting up the parse of one of the fields I had the source and target backwards. That certainly explains why the value was null.

Total user error. I just didn't see it until I started writing the values to the comments.

Thanks!
