Large number of empty Lookup entries in Monitor

I often use the Monitor facility to trace issues in my apps. I have recently noticed that after a form update completes and the app returns to another screen, over 350 Lookup messages appear, each lasting a millisecond or less, and having no apparent content:

The details on each message show only empty strings:

Has anyone any idea what is generating these empty messages and are they anything to be concerned about?

Hi,

I'm Claire from the developer team. I'm afraid it's hard to tell from the description and screenshots.
If it's still bothering you, could you upload your app (or a simplified one without sensitive information if any) so that we can take a closer look at it?

Thanks,
Claire

@clairewu0218 Thanks for your response. I would be interested in the reason for the entries - in case it's pointing to something in the app that should be addressed. Is there somewhere non-public where I can upload the app for your attention?

Hi @biterbit

From your screenshots, it seems that not all the Lookup messages are the same (For example some have data in the colDataDefinitions column). We are not aware of any monitor issues in this area at this moment. It might be helpful to check the form update related functions in your application and see what the cause might be.
If nothing pops out, we'd love to help you troubleshoot further. Could you open a support case for us to help you in that case?

Thanks,
Claire

Hello,

As you refresh things, if it touches any other sources that are shared, and you don't have those controls invisible and or screens, it will start refreshing them all.. And yeah its annoying but that a platform issue, not monitor
