If condition for true runs even though it's false

[DavidLozzi]

I have a basic expression in my flow:

if(not(empty(body('Get_response_details')?['ra7fcccd72d284ee8ae5284e99284ad67'])),json(body('Get_response_details')?['ra7fcccd72d284ee8ae5284e99284ad67'])['displayText'],'N/A')

body('Get_response_details')?['ra7fcccd72d284ee8ae5284e99284ad67'] is empty! Nothing in it. When I run 

empty(body('Get_response_details')?['ra7fcccd72d284ee8ae5284e99284ad67'])

it returns true

if I check the not of that, it returns false

not(empty(body('Get_response_details')?['ra7fcccd72d284ee8ae5284e99284ad67']))

ok, so that's good right? but my if always runs true and errors

InvalidTemplate. Unable to process template language expressions in action 'Send_an_email' inputs at line '1' and column '2397': 'The template language expression 'if(not(empty(body('Get_response_details')?['ra7fcccd72d284ee8ae5284e99284ad67'])),json(body('Get_response_details')?['ra7fcccd72d284ee8ae5284e99284ad67'])['displayText'],'N/A')' cannot be evaluated because property 'displayText' cannot be selected.

Hi @DavidLozzi,

Could you please share a screenshot of your flow's configuration?

What does the formula "body('Get_response_details')?['ra7fcccd72d284ee8ae5284e99284ad67']" represent?

Further, could you please show a bit more about your MS Form?

The error message told that the displayText property could not be selected within the formula "body('Get_response_details')?['ra7fcccd72d284ee8ae5284e99284ad67']" (The Dynamic content representation of a question within your MS Form).

In addition, do you want to get the display name of the question within your MS Form using the "json(body('Get_response_details')?['ra7fcccd72d284ee8ae5284e99284ad67'])['displayText']" formula? If you want to get the display name of a question of your MS Form within Microsoft Flow, I afraid that there is no way to achieve your needs currently in Microsoft Flow.

If you would like this feature to be added in Microsoft Flow, please submit an idea to Flow Ideas Forum:

https://powerusers.microsoft.com/t5/Flow-Ideas/idb-p/FlowIdeas

We could not use the displayText property to get the display name of a question of your MS Form within Microsoft Flow currently. If I understand incorrectly, please let me know here.

Best regards,

Kris

Here's the flow, items highlighted is where I'm trying this expression condition:

Here's the question on the form

https://www.screencast.com/t/AdK66XKwV

I'm confused by your next question.

And no, not getting the display name, getting the value from a likert. If the value exists, it works, if the value is empty because the user didn't respond, then I get the error.

this doesn't solve the problem, but a workaround is to make each choice required.  You have an N/A choice, so it shouldn't be a big deal to require it...

Sadly that’s what I did... is this an If issue or this datatype?

New Flow, same problem:

if(greater(length(triggerBody()?['Snippet']),125), substring(triggerBody()?['Snippet'],0,125),triggerBody()?['Snippet'])

If the snippet is less than 125, it errors on the substring function, even though I tested the greater() statement does return false.
