Issue Summary

Assets custom field doesn't retrieve any values in Automation, even when using the object name (which should work).

Steps to Reproduce

1. Create project (you can use an example project with sample data, such as Assets IT Service Management)
2. Go to the Automation area under Project Settings
3. Create a new rule
4. Select any event trigger, such as Issue commented
5. Add a new action of type Edit issue
6. Select an Assets field, such as Affected Server
7. Try to search for an object associated with it, like exchange* (for the example project of point 1)
8. The field will load forever and you'll see a 400 error in the browser console:

   GET
   https://linux-92270.prod.atl-cd.net/jsm/rest/insight/1.0/iql/objects?iql=objectTypeId=21 and Name like exchange
   Status
   400
   

Expected Results

The object is retrieved successfully.

Actual Results

The field keeps loading and never returns an object.

Workaround

The issue does not occur on (at least) versions 5.17.5 / 10.4.0.

As a workaround, you may try specifying the Assets custom fields and objects to be assigned in JSON format as per Advanced field editing using JSON. Here's an example JSON text of setting an object (ITSMITSM-465) to an Assets custom field (customfield_10204).

{
    "fields": {
        "customfield_10204": [{"key" : "ITSMITSM-465"}]
    }
}
