Error 500 while saving Drafts

Question

Hi,

Pretty often we get Error 500 while saving drafts and the work  is lost.

In the logs I see:

20-Oct-2021 22:30:38.797 SEVERE [https-jsse-nio2-8443-exec-14 url: /rest/watch-button/1.0/watchState/57095474] com.sun.jersey.spi.container.ContainerResponse.logException Mapped exception to response: 500 (Internal Server Error)

But cannot find aditional info related to 20-Oct-2021 22:30:38.797 SEVERE [https-jsse-nio2-8443-exec-14 url: /rest/watch-button/1.0/watchState/57095474] com.sun.jersey.spi.container.ContainerResponse.logException Mapped exception to response: 500 (Internal Server Error)
at com.sun.jersey.server.impl.model.HttpHelper.clientError(HttpHelper.java:273)

[..]

Any help to how further analyze this?

I've seen similar errors related like duplicate record for a draft workflow ,  Error parsing HTTP request header ,or others, but not really the same.

Confluence 7.12.0

Hi Kishan,

Wrong logs attached sorry, my mistake.

It seemswe are being affected by errors coming from use non-unicode characters:

https://jira.atlassian.com/browse/CONFSERVER-53047

Is it possible to use them without these errors? (unsaved drafts in our case)

This is a last Confluence version running under Windows.

Thank you

Hi @Víctor García thanks for the info. The log you pasted seems to be WARNINGs that can be ignored. I think you might be affected with the BUG i mentioned earlier. I would suggest raising a support ticket to Atlassian Support to help you further with this.

Hi Kishan,

It looks the issue is related to non unicode character.

It happens in different browsers (Chrome, Firefox, ..)

And we get entries in the logs like:
