Hi Daniel,

Thanks the ping back.

I know for sure that it's not the other parts of the code / view that is
failing, since removing "async Task<...>" from the method declaration
removes the error permanently. Adding async Task<> makes it fail 2/3 times
approximately. I'll throw something up on github which shows the behavior
and write in the thread again.
