SyncHub 404 Error & "Cannot read properties of null" During Import
Describe the bug When using uSync to import content to our site, the import seems to get stuck on "Post import actions". Looking into the console, I see that reloading the page causes the error messages up to "Failed to start hub". When I attempt to import the content, the final error "Cannot read properties of null" happens.
We have deployed this same build on two different environments, with our Development environment working as expected (no errors in the console) and our Production environment with this error. This leads me to believe it is an environment issue, but I am not sure what would be causing this. Any insight into how uSync works and what might be causing this would be appreciated.
