Flow condition evaluating incorrectly

Posted on by aobr31569

I'm trying to set up a fairly simple flow. Check date of SharePoint column (Calculated column formatted as date) equal to utcNow(yyyy-MM-dd). It wont work. I've created an entry in the SharePoint list with the date of today, and it still shows condition as false.

Even trying on a non calculated column its not working. Yet I have another list/flow and it works fine.

And yet it is quite clearly 01/03/2019.

Re: Flow condition evaluating incorrectly

I'm beginning to think it just doesnt work on a calculated column, which is really unhelpful. I set up one of the standard reminder flows and ran it. Low and behold the following error.

{ "status": 400, "message": "The field 'cdue' of type 'Calculated' cannot be used in the query filter expression.\r\nclientRequestId: d024b19e-de17-4cb7-a73f-5b1d9872c703\r\nserviceRequestId: 3a2cc59e-304a-8000-a457-2945895bf722" }
Changing the column to standard date format and it works.

Re: Flow condition evaluating incorrectly

Thanks, tried the updated expression and get a new error.

Unable to process template language expressions for action 'Condition' at line '1' and column '2541': 'The template language function 'formatDateTime' expects its first parameter to be of type string. The provided value is of type 'Null'. Please see https://aka.ms/logicexpressions#formatdatetime for usage details.'.
I did also try removing the null/blank fields in CalibrationDue, but still get the error.

Unable to process template language expressions for action 'Condition' at line '1' and column '2541': 'The template language expression 'equals(formatDateTime(body('Get_items')['Calibration_x0020_Due'], 'yyyy-MM-dd'), formatDateTime(utcNow(), 'yyyy-MM-dd'))' cannot be evaluated because property 'Calibration_x0020_Due' doesn't exist, available properties are '@odata.nextLink, value'. Please see https://aka.ms/logicexpressions for usage details.'.
Even though it clearly does exist and is referenced in the output of get items.

Hi @aobr31569

Try this:

subtle change with use of "?" which allows null. if it were one item, it wouldn't matter. now it is items there looks to be some with out a due date in your JSON.

equals(formatDateTime(body('Get_items')?['Calibration_x0020_Due'], 'yyyy-MM-dd'), formatDateTime(utcNow(), 'yyyy-MM-dd'))

Otherwise, you may have to enhance your condition to say if ['Calibration_x0020_Due'] is not null or empty.

I say this as your JSON has:

New_x0020_Owner& New_x0020_Owner#Claims it seems ...

Error:

The expression is working and doing it's job. the empty vallue needs addressing hence I'd try this.

Re: Flow condition evaluating incorrectly

Thanks again, I think I understand what the expression is doing. (CalibrationDue = utcnow) = true. But it always results in an error.

I'm using 'Get Items' rather than 'Get Item' if that makes much of a difference. I did change that in the expression, but it still errors.

Get items is working, i've checked the output.

Basically I have a list of 465 items requiring calibration. I want to check the calibration due date against the current date, and change another column status as a result. (I have another workflow that checks the due date and sends an email when its within 30 days and then 7 days, these use dynamic content and a single expression that seems to work)

I need to get to grips with expressions and formats because the power of flow with SharePoint lists seems to have huge potential, but its not quite as simple as I first thought.

Hi @aobr31569

Sorry for the jargon, WDL is Workflow Definition Language. More information on expressions here

So, thanks for the information as I believe what you are looking for is:

equals(formatDateTime(body('Get_items')['Calibration_x0020_Due'], 'yyyy-MM-dd'), formatDateTime(utcNow(), 'yyyy-MM-dd'))

Now, I am assuming you are using a SharePoint "Get items" and it's named as the default, but if not, you will need to tweak that(body('Get_items')['Calibration_x0020_Due']), but you're on the right track in terms of date format.

Something like the above , equal to true should work if indeed you want to work in the most with date format of 'yyyy-MM-dd'.

You may not need to format the date time but when you read the references below that will shed more light on it over all as it could become:

equals(body('Get_items')['Calibration_x0020_Due'], utcNow())

Information here:

utcNow()

formatDateTime()

Standard Date and Time Format Strings

Re: Flow condition evaluating incorrectly

Thanks for the suggestion, as I'm a Flow beginner what is 'WDL'?

I tried using the expression you suggested, but it always says its invalid. (I did change Last Cali... to the full string).

Portion of JSON code.

"Calibration_x0020_Due":"2011-07-24T23:00:00Z"

Even though the column is formatted as date only, its returning date/time.

Re: Flow condition evaluating incorrectly

Hi @aobr31569 , I will try to assist.

what's the actual WDL for:

As I would try

equals(<Last Cali...>, utcNow(yyyy-MM-dd))

then make that equal to true(expression).

That may work or post the output of the SharePoint connector JSON that has generated <Last Cali...> and I will do my best to assist.
