Trouble updating PIPoints via the PI WebAPI's value stream

Hi all,


I am having troubles doing updates on PIPoints via the PI WebAPI's value stream. This has worked in the past so I think it is version related.


I am using PI WebAPI 2018 Version


So for example, when I try an update via following URL:


WIth payload:



I get the error: The remote server returned an error: (400) Bad Request.


When I do the same via the recorded stream, all is fine. So it is not a rights problem.


Does anybody have an idea where to look to solve this? Or can anybody reproduce this problem?
