Write API issue

Feedback / Issues and Bug Report / Bugs or Issues

I am able to write data to the Canary Historian, but as soon as the session token is revoked (either by timeout or by revokeSessionToken) a 'No Value' value is written with 'No Data' quality. This did not happen in Version 23 - it just started happening in Version 24. How can I stop this from happening?

    Hi ,

    That is a default setting. If you want to turn it off, you'll want to specify the autoWriteNoData parameter in  your settings array and set it to false when you make your \getSessionToken call.

      Thanks @Steve Mason  - missed that. apparently that wasn't part of ver 23. Just out of curiosity, why did that default to true instead of false?

      Not sure. That is the default setting in v23 as well.
