Runtime error on node registration

Support Installation and Deployment

I recently set up an instance of Tyk in an Ubuntu VM according to the doc “Install Tyk Pro Edition on Ubuntu”. Everything seems to be set up correctly, but whenever the gateway tries to start, it throws the following error:

==> tyk-gateway.log <==
[Apr 11 14:11:30] ERROR Failed to decode body: json: cannot unmarshal string into Go value of type []main.Policy
[Apr 11 14:11:30]  INFO main: Gateway started (v2.0.0.0)

Any advice on what might be causing this?

Do you have something else running on the same port? That’s what that panic usually means.

netstat didn’t show anything, but that has to be it. Change the port to 8090 and it’s no longer crashing. Thanks!
