detect blank value in microsoft flow

[eagle dorothea]

Hi Anyone,

How can I add a condition to check if a field has a blank value?

I use @empty(triggerBody()?['Choose_x0020_Approval'])

Even I have value on it, it keep detect I have blank value, so approval flow keep coming.

what I want is if value not blank, approval will run

Note: my column name is "Choose Approval' somehow, of its auto generate become "Choose_x0020_Approval"

For a Text column I use this condition:

Kind regards, John
