Invalid Template Error

Long time reader, first time poster!  I'm hoping someone can help with what seems like an easier flow, but I can't figure out.

 

I'm trying to build a scheduled flow that will send an email based on the age/status of SharePoint list items. 

 

To qualify for the email trigger, the list item would have been "open" for > 60 days and "not modified" for > 30 days.  They would also not have a "status" of 'complete', 'duplicate', 'won't fix' or 'canceled'. 

 

I'm running into the following error when testing:

Unable to process template language expressions for action 'Condition' at line '0' and column '0': 'The template language function 'greater' expects two parameter of matching types. The function was invoked with values of type 'String' and 'Integer' that do not match.'.

 

I have verified that the SharePoint list is set to a number format for both of the > fields (these are both calculated columns set to number format).  The images below show the current setup and the result of the test.

Here are the test results.

Hi @KPenn ,

 

Make sure your datatype of output and comparison is correct.

You can check output in sample compose block for each item. 

I feel 'Modified On' is string value and you mentioned 30 which is numeric

 

Use this (replace with your column name)

greater(int(formatDateTime(triggerBody()?['Last_modified_on'], 'dd')), 30)

and equals to true

 

Hope this helps

Hi Ethan,  

I was referencing a calculated column which shows the number of days aged, rather than using the date.  

 

To test your idea, I replaced both numeric fields/parameters with the date fields instead, then used the expression you provided.  Unfortunately, I received a different error:

KPenn_0-1684353943746.pngIt looks like is still requesting a 'string" type. 

 

Hi @KPenn ,

 

First check the outputs of both the data in a compose action. 

You can verify the data coming in those fields.

Once you see both items are matched then you can proceed with putting them in your condition.

 

int(formatDateTime(triggerBody()?['Last_modified_on'], 'dd')

I think you should get numeric day as number and provide Greater than 30 in condition.

 

Once everything is validated, you can remove compose block if you want
