Do Until Function with Yes/No-condition

Hello together

I am creating a flow in which a Do Until function is repeated until a field in Sharepoint is changed from No to Yes. During this time a notification email will be sent to the responsible user until he also changes the above mentioned field from No to Yes. I have tried various methods, but the flow does not recognize that the sharepoint field has been changed to Yes and therefore remains stuck in the do-until loop forever.

Hello @erowa 

Share the full flow design so that I can repro the issue and help you further .


For example if the basic view to generate the advanced function is as below, will not work ::

@equals(triggerBody()?['SupervisorApproved'], 'true')

And the problem with this is that it checks for a string 'true', instead of a boolean value for true. Changing the function to removing the quotes should help::

@equals(triggerBody()?['SupervisorApproved'], true)

The above should check for actual boolean true instead of a string 'true'.

Hello and thank you for your response


It does say: 

@equals(outputs('Element_erstellen')?['body/Qualit_x00e4_tskontrolle'], true)

Here is my flow, unfortunately it is in german:

Hello @erowa 

In the screenshot can see that you are trying to set the true as Expression value. Try as below and check ::Keep the string value within quotes::

@equals(outputs('Element_erstellen')?['body/Qualit_x00e4_tskontrolle'], 'true')

The way you are trying to do it isn't going to work. Because it is not doing another lookup every iteration of the loop, it is using the same data that it began with when the flow executed. If you want to check if the field has been updated, you will need to look up the value of the item again within the loop. 


You will have to base your do..until loop on a variable that you set within the loop when the value in your SharePoint is updated.

I have a message saying that an action to initialize a variable can only take place at the top level. Could you perhaps show me an example?

When I do it like this, it doesn't work. Is there a different solution?
