Moralis Server UI: getting 500 error when saving new "Sync and Watch Contract Event"

[ggamir]

The 500 error happens when attempting to save new contract events on the moralis server UI under "view details" > "sync" tab > "Add New Sync" > "Sync and Watch Contract Events"

I added around 80 contracts events successfully to sync before at some point it stopped working with accepting new events. New contract events are not added, and looking at devtools console shows that the server is giving back a 500 error. I started adding them very quickly, but otherwise I'm not sure why it is breaking.
