Flow with a checking condition a true/false value which always returns false

[Preetish]

I have a requirement on Microsoft Flow. Depending upon my requirement, I have a SharePoint List and in that list, I have one Yes/No field column.

When I am trying to put this Yes/No field Column in flow Condition is equal to true/false or 0/1, Always the condition returns as "no" even if it is true. How can I resolve this issue?

Below is the flow screenshot:

I don't know if it's related, but I have a flow I'm working on, and last week, my conditions where working perfectly, but now they seem to return false (no) and I can't figure out why. At this moment I'm still trying to figure out what's wrong.

This should return true, if the three fields are cleared, but it always returns false, even if they are cleared.

I can get it to return true (yes), if I change "is equal to" to "is not equal to".

As I said, this was working last week.

Hi @Preetish ,

Could you provide more details about the field you mentioned?

Do you have any special treatment for it?

Basically the return value of Yes/No field is true and false.

I did a test on my side. If Yes is selected in the field, the result of Condition judgment will be true.

Image reference:

You could try adding a Compose action on Condition to output the return value of the current field to see if this field selects Yes or No.

Please take a try and see if issue still exists.

If the problem persists, please provide Flow run history, including the results of Compose output so that we can analyze the problem.

Best Regards,

I got the same problem. Adding "compose" fixed it 🙂

I have the same issue.  I tried adding compose to the condition, which returns the Yes/True as it should, but it still prompts false.

The op's screenshot shows the word "true" being manually added which won't work. Has to be an expression you can look up. Not very intuitive and poorly documented as usual.

As the blog post that @acewmu points to, and the screenshot that @webbrewer shows, you have to add the 'true' part via an expression:

One thing to add is that (for me at least) when you type true in the expression input box and click the autocompleted 'true' (in blue text with the little icon next to it on the left as shown in the image above), then click OK, you might get an error saying "The expression is invalid". IGNORE THAT! It's an annoying little bug. Simply click OK to close the error dialog box and then click OK underneath the expression input box and, this time, the "error" will not appear and true will appear in the condition box in a pink box with the 'fx' icon next to it on the left (as shown in the image above)

Thought I would add that if you are using "experimental features" I am showing a bug where the true/false/null functions show up as undefined.

Thank you for this - I could not figure out why I kept getting undefined!

I have the same issue. I can see that the output from a http request is "true" but input in the copose block is always false. I guess it has to do with the parsing of the http request.

Here is the raw http:

Show your condition in edit mode.

It pretty simple. A user fills a form with requested sharepoint folder name, the flow checks if the folder exists (true/false) an at true it replies in teams, if false it creates the folder and renames it.

[VictorIvanidze]

Wrong "true" - see webbrewer's answer above.

[RoReAl]

I wish it was that simple, i have tested the expression true before, I dont get it right anyway.

I have tested to compose as well but the compose only sends the same true/true or false/false to the Condition.

[RoReAl]

I do get the red frame blow sometimes. And I cant click on the Peek code but maybe thats something that should be.

[VictorIvanidze]

Try to use bool() function in the left side of condition.

[RoReAl]

Thanks for the effort, but no. I added bool('true') and made sure like above to use the functions that com in the droplist, but i get the red box again. The result is true in the http request, but the input and output in the Condition is false:
