What is the proper way to use the condition function if I want to look for a field that has a blank value?
We can use Workflow Definition Language to configure the Condition, please check this documentation for a reference:
About how to check if there is a blank value in the field, please consider to use Empty function. Empty function returns true if object, array, or string is empty.
I create a simple flow to send email when a field has a blank value.
In the Condition, I configure the Empty function as @empty(triggerBody()?['Model1']?['Value']).
Note:['Model1']?['Value'] is value for the column “Model1 Value”, I get it from the dynamic content.
I run the flow for several times, and it works as expected on my side.
Please try it on your side. Please feel free reply if you need more help.
I guess that you are trying to return to the Basic mode. This error is just saying that you cannot return to Basic mode from Advanced mode.
Please add the following action and save the flow, then run the flow, I guess it will work as expected.
