Unable to get data from Sharepoint online List

[RoelVB]

When trying to load a list from Sharepoint Online I get this message:

"DataSource.Error: We couldn't parse OData response result. Error: A null value was found for the property named 'Monteur_x0028_s_x0029_Id', which has the expected type 'Collection(Edm.Int32)[Nullable=False]'. The expected type 'Collection(Edm.Int32)[Nullable=False]' does not allow null values."

I've searched the internet and everybody is sugesting to change de API version from 15 to 14 to solve this.

But after changing the API version I get this message:

"DataSource.Error: SharePoint: Request failed: The underlying connection was closed: An unexpected error occurred on a receive."

What else can I do? I cannot remove this column.

Hi @RoelVB,

You connect to SharePoint Online List from Power BI Desktop and get the above error message, right?

Power BI throws the above error when your list has Multiple values in a field such as Multiple choices, it has been identified as a known issue with SharePoint and the team is working to resolve it. As a temporary workaround for this issue, you can fill these null values or disable allow multiple selection. For more details, please check the following similar thread.
