I have been trying to load Board Column data from Azure Devops into Power BI but I am getting the following error when trying to expand the BoardsLocation field:
DataSource.Error: OData: Request failed: The remote server returned an error: (400) Bad Request. (VS403483: The query specified in the URI is not valid: VS403489: The Analytics Service doesn't support key or property navigation like WorkItems(Id) or WorkItem(Id)/AssignedTo. If you getting that error in PowerBI, please, rewrite your query to avoid incorrect folding that causes N+1 problem..)
I am connecting using Odata and this is how I am doing it in a dataflow:
OData.Feed("https://analytics.dev.azure.com/{org}/{project}/_odata/v3.0-preview", null, [Implementation="2.0",OmitValues = ODataOmitValues.Nulls,ODataVersion = 4])
The above expands on other fields like WorkItems fine but it is throwing the above error and I cannot understand why.
It's recommended to rewrite the query to avoid the N+1 problem, which is causing the request to fail. You could try a different approach to retrieve the Board Column data, such as using the Azure DevOps REST API instead of OData.
Hi @Anonymous,
It seems like the error is related to the query specified in the URI not being valid. The Analytics Service doesn't support key or property navigation like WorkItems(Id) or WorkItem(Id)/AssignedTo, which might be the reason why the BoardsLocation field is not expanding correctly.
Hi Sahir,
Thank you for your replies.
I think the API route will be very difficult to maintian and develop because I am trying to get historical work item revisions of the board columns for a huge amount of data. The API docs show that each API call retrieves the WorkItemRevisions of one WorkItem at a time.
Why is it that the data can be located in WorkItemRevisions (BoardLocations column), but it cannot be expanded? What is resulting in the N + 1 problem? I have even tried to expand the BoardLocations column for one WorkItem at a time and it still results in the same error.
