Hi Pladavm,

 

Please try to configure the condition as following.

 

In edit mode, select Has Attachment from the Dynamic content, then click the Edit in advanced mode and configure the function with @equals(triggerBody()?['HasAttachment'], bool('True')).

I have tested it on my side and it is working as expected. Please try it and let me know if it works for you.

You can no longer do this as the "Advanced Mode" feature has been deprecated. Could you please advise how this particular use case can be done using the dynamic expression builder, and without advanced mode? I also need to validate if there are attachments using a condition. Thank you!

I have done it this way and it worked absoutley fine without the complex of formulas.

So it's a matter of using "true" instead of "True" then. 👍😊

This is the solution, add  bool('True') to the expression and then back in basic mode it will look like this:

@BFitz Thank you for posting the solution!!  

Nnnope. 

Has Attachment | is equal to | bool('True') 

(with bool('True') set as an Expression) doesn't work either (at least not for me); defaults to a False result regardless of whether there are attachments are not.

 

According to the thread we're in--and this one--it's still a mystery as to how to get Has Attachment to work (or at least by using the excact values it's looking for). So might as well consider Has Attachment broken. (Or, at best, unreliable...because it reportedly only works for certain people, and only when used in unorthodox ways.)

 

From what I can tell, this is the only reliable way to check for attachments:

length(AttachmentsVariable) | is greater than | 0

(Annoyingly, as you're typing out this expression, you can't click Attachments from the Dynamic Content list to autopopulate the Attachments "expression" value into your expression. But you can instead just manually type the Attachments "expression" value; one of many weird bugs when trying to create expressions--the primary bug being it telling you the expression is invalid the first time you click "OK", then it works when you click it a second time.)

 

In my case the formula is:

length(triggerOutputs()?['body/attachments']) | is greater than | 0

This is all kind of silly, because checking if  length(AttachmentsVariable) is greater than 0 is exactly what I would have checked for in the first place, if I hadn't spotted the Has Attachment variable that I wasted way too much of my life wrestling with

@wad11656 it is working for me.  I just did another test and it works.

This is working for me as a trigger condition:

@equals(triggerBody()?['{HasAttachments}'],bool('True'))

Hi everyone,

 

I know it's an old thread but I had success and thought I would share. I belong to that group of people for whom this does not work as expected. I tried equal"true", "True", "bool(True)", no joy. 

 

Then, I tried this from another thread and this worked finally! HasAttachment is not equal to null (null as an expression!)

I hope this helps!

@krisztina 

 

Are you using bool('True') or bool(True)?  The true needs the single quote.  

I am not sure if I tried with or without single quotes, I copied it from one of the threads. 

I will stick with the not null option though, I tested it and it finally works. I will not touch it until it breaks again. 😄

That's good that it is working for you.  When you say, "copied it...", did you copy and paste it into Power Automate or did you type it in?  The reason I ask this is because I've had issues with flows not working correctly when I copy and paste.
