The screenshots really aren't clear as to what is on the form or what you're trying to do.  I see 2 screenshots showing your tests that you're trying to run.  One of them makes no sense though.  It opens an incident form and then attempts to set values on the catalog task table.  ATF can only set field values to fields that are actually present on the form view.  Is the 'Assigned to' field included on the form you're running the test against?  Are the tables you're working on consistent across your test?

Sorry the second is not the right image. I attached the right

The flow I want (I want to create a TC to validate the "states")

1-Set field values/validate

2-Click on Save button and the form will be saved

3-Add value to the field "Assigned to" and save

4-Form will be saved and the "State" must be from "Queued" to as "In Progress"

There is that error message on step 3 (error: FAILURE: Unable to set field 'assigned_to' to value 'f5d14a4d0f1a13004bd9534f62050e1e'. Field 'assigned_to' is not present on the form. See screenshot) .

But as the image "final2" I added a value "Aline Souza" to be added on "Assigned to" field.

Is the 'Assigned to' field available on the incident form?  It's not enough to have it on the table, it needs to be part of the incident form view for the test to work.

The error message is telling you that you need to configure the incident form and add the 'Assigned to' field there.

If you can post the screenshot of your incident form that might help.

Yes when I select the table that appears and on screenshot the ATF got after run as image "fail3"
