Cannot use Excel field

Hi all,

I've build a flow that creates tasks in Planner from Excel. Everything works great appart the fact that I cannot use either in the Title nor in the Description of the newcly created task, a specific column from my Excel table.

This specific column is formated as Text and contains values similar to '1.3.2.15.'

The error I get is:
"The request is invalid: A null value was found for the property named 'title', which has the expected type 'Edm.String[Nullable=False]'. The expected type 'Edm.String[Nullable=False]' does not allow null values."

Any day saving ideas?

Re: Cannot use Excel field

I suspect you have an empty row in your Excel table. But the easier method to troubleshoot is to look at the output of your list rows action from Excel. To examine what is being passed to your create action.

Re: Cannot use Excel field

Thank @Paulie78 for pointing this out, but I can't seem to understand the mistake here. By the way, there are no blank rows in the table.
Along to flow, there is an 'Create a Task' action that produces bad request. Would it be possible to take a look at the OUTPUT/Body I got?

{
  "error": {
    "code": "",
    "message": "The request is invalid:\r\nA null value was found for the property named 'title', which has the expected type 'Edm.String[Nullable=False]'. The expected type 'Edm.String[Nullable=False]' does not allow null values.",
    "innerError": {
      "date": "2020-11-15T07:44:15",
      "request-id": "7fb861d4-9547-4b95-964d-ae060a669181",
      "client-request-id": "7fb861d4-9547-4b95-964d-ae060a669181"
    }
  }
}

Re: Cannot use Excel field

The error message is clear, it is trying to create the task for you, but the value it is being supplied for the title value is null.

So the input you are providing to it is invalid. Can you provide a screenshot of your flow. I still suspect you have an empty row in Excel, I would guess at the end of the table. If you add a filter to your Excel results, you could ensure this never happens.

But post an image of the flow and lets have a look. Ideally post the output of your list rows action from your run history also.

Re: Cannot use Excel field

Just tested to use a semicolon before the field and it worked. See below in Field Title how the two variables are inserted. The second one was the one not working before.

You have fixed the error message, by hard coding a value. But check the results carefully, you may have created a task that has a title of just a semi colon.

Re: Cannot use Excel field

Everything is ok in the title apart from the semicolon itself 🙂
But why are you talking about hardcoding? I just inserted the variable in the Title field.

Re: Cannot use Excel field

So you didn’t have the variable in the title field before? Makes sense now.

I am talking about hard coding because your initial error was that they create task action was complaining about null.

if you have null values but you also have a semi colon in the field (which is hard coded). You may end up with a task whose title is just a semi colon.

Don’t worry about it, glad it is working for you 🙂
