    I had the same issue for my Submission Date column in sharepoint. when i was try to populate the date picker in canvas app from this column. Value in sharepoint was correct but not reflecting in power apps. it was working fine in Dev but had this issue in prod (earlier it wasn't there)
     
    I simply fixed this issue by change my Date column in sharepoint to include Time.

    Hello, when I got this error on the field that imports data from Dataverse, I just deleted and re-added that feild. And the error disappeared. Not sure if this is going to help you guys but I wanted to share my experience regarding this.

    IfError(IsBlank(Text(DateTimeValue(ThisItem.DateValue),"mm-dd-yyyy")),Blank(),Text(DateTimeValue(ThisItem.DateValue),"mm-dd-yyyy")
    )

    Then make sure that from the settings, Formula-level error management is turn on.

    Hi @Anonymous ,

     

    For this issue, it is clear that you are playing canvas app and after maybe you type the datetime value, which is not valid for power app, this error showed up.

     

    If this is the case, you might need to provide the date format at the same time: Please try below formula

    Text(Your_own_date_time_value,DateTimeFormat.UTC)

     

    Best Regards,

    Hen Wang
