Error - 54419
Sync: Number of subscriptions per connection is over the limit
An SDK attempted to open and listen for updates for more than 2000 objects.
Possible Causes
A programming error has generated many queries in place of one.
Your app has created too many LiveQueries over time (often a problem in single-page apps).
Possible Solutions
Make sure you're only issuing queries for information that you need.
When your UI no longer needs a query, use the close() method on the LiveQuery object to unsubscribe and release the corresponding Sync resources. See the SDK Documentation for details.
