Unable to update asset attribute with type select

[Bryan Spangler]

First off, I am completely new to groovy script. I do have some coding experience (in college) So I am not as well versed in this as I'd like to be. 

We working on tracking our laptop assignments through Jira issues. Open a ticket to check it out and close the ticket to check it back in. I have an automation that kicks off a script to "check in" the computer. It updates our assets based on custom fields in an issue. But I have not been able to figure out how to update an asset attribute called Lifecycle, that is a Select type. As far as I've been able to find I should be able to update them by passing in a string ('In Production' below) while the rest of the attributes work (a user reference, and a boolean) the select list does not. The script is below. Any help would be greatly appreciated.

Thank you

def coAsset =  issue.getCustomFieldValue('Keytemp')

def asset = Assets.getByKey(coAsset)

asset.update{

    clearAttribute('Checked out to')

    setAttribute('Checked Out', false)

    setAttribute('Lifecycle','Recertification')

}

I moved the setAttribute for 'Lifecycle' to the beginning of the update and it works now. No idea why this works but I guess I figured it out.

Am still getting 

Script function failed on Automation for Jira rule: Laptop checkout, file: autocheckout.groovy, error: java.lang.NullPointerException: Cannot invoke "com.riadalabs.jira.plugins.insight.services.model.ObjectTypeAttributeBean.getType()" because "ota" is null

in the automation log. Anything I can do to get rid of this error?
