Issue Summary

When we are using variables like  {foundcardfirstmemberusername} or {triggercardfirstmemberusername} with a lookup a card or find a card action, we get no result.

• It works when used with a simpler rule that does not involve a lookup.
• Using variables like {foundcarddescription} is working with lookup/find card actions.

Steps to Reproduce

1.  use an automation rule like below 

   when someone is added to a card, find a card titled "{cardname}" in list "Candidates" on board "First Board", link the cards together, and set custom field "user" to "{foundcardfirstmemberusername}"

Expected Results

We should be able to update the custom field with the member username.

Actual Results

The custom field is cleared, and no value is updated.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
