Hello. When exporting confluence xml spaces, I get an error when starting the conversion.
I have not found a solution to this problem on the forum.

Hello @Shekel,

Thanks for the report, it is a bug in Confluence Migrator Pro: Ignore events related to migrations not started with Confluence Migrator Pro · Issue #111 · xwikisas/application-confluence-migrator-pro · GitHub. I’m committing a fix today.

I see three ways to avoid the issue:

  • Use Confluence Migrator Pro to migrate your content instead of Filter Streams Converter
  • Wait for the next release of Confluence Migrator Pro, that will contain a fix for this issue
  • Uninstall Confluence Migrator Pro and make sure confluence-xml is still installed, or install it
