why does nesting smart values not work for string extraction?

Question

Hi,

i created an automation to detect some pattern in issue summary and cut it out, but I can't make it work. For unknown reason, the nesting of two smart values doesn't work, while other contributions suggest it should ( like here and here):

Here's the flow description:

1) create a container variable

2) make sure it's a numeric:

3) extract a part of the description (it's a long string). I also tried the function "issue.summary.right()", with the same result

4) check the logs: no text has been read, as if issue.description.substring() wouldn't work with a smart variable as parameter. When I input an explicit integer like 5, it works. With the smart values, it doesn't. As you see in the logs, I made sure the value is a numerical.

Any clue or help would be highly appreciated.

PS: this is the ticket I use for testing purposes, how it looks like. As you see, summary and description are far from being empty:

Hi, i got the solution from Atlassian support:

you can use the below smart value to get the ID from the summary. Also, indexof function gives you the position of a particular character in the string. Match function:

{{issue.summary.match(".*(#[0-9]{1,}).*")}}

it gives: #2345 - It search for # followed by at least 1 digit

I checked the articles that you have referred and nesting using temp variable *now.plusBusinessDays(varTemp.asNumber)* only works with the number function, not with the string function "substring()".
