JMWE - "Cannot read property 'match' of null" er

[Dan H]

We are getting this error constantly now out of the blue with one of our JMWE Post-Functions, after having this working perfectly fine before;

Set field value - internal-error - Cannot read property 'match' of null

ignoreEmptyValue:false
conditionalExecution:false
sendNotifications:false
createMissingValues:false
valueIsJSON:false
_needsRefresh:true
value:"{{ issue | sprints("active") | last | field("id") }}"
appendValues:false
_modified:"2019-06-13T11:16:22.189Z"
copyOnlyIfNotSet:true
fieldId:"customfield_10007"
runAsType:"addonUser"

Any ideas why this could have suddenly broke/changed on our workflow? :(

[David Fischer · Accepted solution]

If the destination field (customfield_10007) is the Sprint field, then this error will happen if the current issue doesn't belong to any active Sprint, because you're basically setting the spring field to [null]

Instead of logging an error, this should in fact clear the Sprint field. This is a JMWE bug that will be fixed in the next version.

In the meantime, you can avoid these errors by using Conditional Execution with this conditional execution script:

{{ issue | sprints("active") | last | field("id") }}

Thanks for your response David!

And apologies, only just seen your comment now (guess I have my email notifications turned off or something).

I'll continue to keep an eye on the error log but hopefully everything is all good now.
