What does KeyFoundInDeletedResourceKeyCacheException mean?

[MarkTh]

I had a streaming dataset with history switched on, that I pushed data to using the code sample in the "API Info" dialog. That worked fine.

I deleted the dataset and recreated it with the same name, fields and data types and also history on.

Now when I try to push the same data as before (using the new Push URL of course) and now I get a 401 with the above error.

Any ideas?

Looks like a bug in PowerBI (web UI): The key in the Push URL field is oddly missing 8 charachers compared with the actual push URL in the cURL / PS examples.  If I use the key in the examples rather than copying from the Push URL field, it works!
