We have a site we’ve upgraded to 9.1.2 from 8.5.9 that won’t run Tasks that include page indexing like Generate Sitemap or Reindex Content.
The dashboard page returns the error:
Failed to send an update.
If run in the command line we get:
Generation of sitemap.xml started. In HandleMessageMiddleware.php line 128: Handling "Concrete\Core\Command\Task\Command\ExecuteConsoleTaskCommand" failed: Failed to send an update. In Hub.php line 104: Failed to send an update. In HttpClientTrait.php line 451: Invalid URL: scheme is missing in "". Did you forget to add "http(s)://"?
Any ideas where to look for a solution?
