Set multiple services to Affected Services field based on a string

[Wesley Wong]

Similar to this previous question: 

https://community.atlassian.com/forums/Jira-questions/Set-multiple-services-to-Affected-Services-field-based-on-a/qaq-p/2540689

I am trying to achieve the same thing, except that my list of values are from a drop-down list.

I have a custom field multiselect drop-down - {{issue.customfield_10873}}

I use the look-up objects action to look-up the Services Schema using the query

Name in "{{issue.customfield_10873.name}}"

And then I use the Edit Issue action to set the value of the Affected Services field

{ "update": { "Affected services" : [{"set":[ {{#lookupObjects}} {"id":"{{Service ID}}"} {{^last}}, {{/}} {{/}} ] }] } }

This works when only 1 service is selected from my custom multi-select drop-down field but when more than 1 value is selected, the rule does not set the Affected services field.

Any ideas?

Thanks
