[IGN-5303]Error retrieving diagnostics when opening a tag

travis.broussard · December 8, 2021, 7:39pm

Has anyone encountered a recurring error popup when opening a tag in the Designer’s tag browser?

The error message simply states “Error retrieving diagnostics”.
Here is what is listed under details:
GatewayException: Unable to read response from Gateway.

Are you retrieving tags from a different version of Ignition via a remote tag provider? Did you recently upgrade any gateway(s) involved?

travis.broussard · December 8, 2021, 8:02pm

We did recently upgrade the gateway to 8.1.12. I did not upgrade my Designer. Would that cause this issue?

Edit: The tag provider is on the gateway. Nothing special there.

This just looks like a bug on our part. Can you open a ticket with support and probably provide your tag export or gateway backup?

travis.broussard · December 8, 2021, 8:12pm

Will do!

bruno.nunes · January 10, 2022, 10:20am

Hello,

Please do keep us informed, having the same problem exactly.

On our case, this is happening on tags with “History Enabled” only.

Thank you,
Bruno Nunes

travis.broussard · January 10, 2022, 2:58pm

Certainly. I submitted all of this to IA Support and have worked with them for weeks. We haven’t arrived at a solution yet, so it may well just be a bug IA devs have to squash.

Kevin.Herron · January 10, 2022, 3:01pm

This is definitely a bug we need to fix, if support hasn’t made that clear I’m sorry.

I’ll try to pull it into this upcoming sprint.

travis.broussard · January 10, 2022, 8:14pm

Sounds good. Thank you for the update!

bruno.nunes · January 11, 2022, 12:05pm

Sorry to revive this again, but just an update. On our case, it seems it was just a configuration mistake. We had defined history enabled for a couple of test tags, without setting up the storage provider. Once we defined it, the error stopped popping up.

agavino · March 24, 2022, 10:00am

Hi, is it resolve?

Kevin.Herron · March 24, 2022, 1:17pm

Sorry, it doesn’t look like it has been fixed yet. I’ll bump the priority a little.

I’m reading on our ticket that if you restart the tag you should be able to access the diagnostics afterwards.

tyler.bennett · April 20, 2022, 3:24pm

I’m running Ignition 8.1.16 and just ran into the same problem when I started enabling history on tags.
the error pops up as soon as I try to save a tag configuration for which I just enabled history and every time I open the tag configuration after that, until I disable history.
Initially I had missed specifying the history provider but correcting that does not appear to resolve the issue.

The icon beside the tag indicating history is enabled does not appear until I restart the designer. Also, it does not disappear when I disable history until I restart designer.

Is there a known fix or work around?
