Jira automation smart value for concatenating string not working

[Jacob Turley]

I have a deployment automation that has a name like "Release v1.14.30".  I'm trying to create a fix version that ends up like this:

momentum:1.14.30

The smart value is this: {{"momentum:".concat(deployment.name.substringAfter('Release v'))}}

However, I am getting this error:

Error rendering smart values when executing this rule:

Failed to get value for "momentum:".concat(deployment.name.substringAfter('Release v')): {{"momentum:".concat(deployment.name.substringAfter('Release v'))}}

I would have assumed I can concat onto a string, but not sure if I'm doing something else wrong?

Hi @Jacob Turley 

You cannot use a literal value (e.g., "momentum") as the starting value in the expression.

Please try storing that literal in a created variable first, and then use that to create your new version name.

Or...build the entire thing in the variable in one step for use later:

• action: create variable
  • name: varMyVersionName
  • value:

momentum:{{deployment.name.substringAfter('Release v')}}

Kind regards,
Bill
