Split function not working in Jira automation for a custom field

[Thushan Kalhara Withanage]

There is a custom field called Reported Version and there is a value field under it. Need to split the column by "." character to compare the last part with a constant in an automation function.

Custom field name : "Reported version"

Field structure in Rest API : 

"customfield_15753":

{
"self": "some value",
"value": "A.B.0",
"id": "1111"
}

Tested with following. But it does not work as expected.

{{issue.fields.customfield_15753.value.split(".").get(2) = "0"}}

Hi @Thushan Kalhara Withanage 

I struggled with the same issue, and decided to share here although it's a quite old post.
It appears that split, replace, left, ... functions do not work for custom fields.

This is the way I managed to make it run: use a smart value variable in between...

1. Create a smart value variable with the custom field content populated
2. Use the split, replace, left, ... functions on the smart value variable
3. Use the smart value variable anywhere in your automation (e.g. change an AQL attribute in my sample pic)

Hope this helps someone, and do share better methods that anyone might have.

Thanks and cheers

Hi @José Nogueira , 

It makes no sense that we need to go to such an extent, but your solution works !

I was struggling with the "from" object from the changelog, it felt like it's neither an array (I couldn't loop through its element), nor a string (I couldn't split it to turn it into an array)

But storing it into a variable, ex :

{{changelog.myCustomField.from.remove("[").remove("]")}}

 allowed me to save the IDs as a comma-separated string (without the brackets), ex : 

1234,1235,1236

on which I could finally get an array with a simple split

myCustomFieldFromVariable.split(",")

I'm just putting the snippets here to help if someone googles it 

Thanks a lot José !

And I wish Atlassian could update the documentation to make it clear

I haven't tried, but you're doing two things in that expression: splitting and getting the 2nd components plus comparing it to a string literal. If I were you, I'd try if the split-and-get works. If it is, then the problem is with the comparison.

For that, I'd try the Advanced Compare Condition component in the rule.

Hi @Aron Gombas thank you for the reply. Yes, the problem is that the split function does not works as expected. Do you have any suggestions on that, how to split a string value from a custom field in Jira.
