Tyk Gateway error - Failed to decode body: json: cannot unmarshal string into Go value of type []main.DBPolicy

Interestingly reload of APIs doesn’t seem to be working. So when I add or edit an API in the dashboad, I see this error in the gateway logs:

[Aug 25 14:47:02] ERROR pub-sub: Payload signature is invalid!

Restarting the gateway results in the new or edited APIs being loaded.

Not sure if this is a bug as a result of the mutex locking changes?
