Agent suddenly returning (instance : 0x0x200114c4)

Just started getting some strange behaviour: my agent was all working fine, returning a string to the device. Suddenly it’s returning:

(instance : 0x0x200114c4)

I haven’t touched the code at all, just suddenly started returning this strange string.

Any ideas?

It seems to be to do with response.body. It was working fine but now returns the above. If I just put a string, for instance “hello” then it returns the string to the device. I’ve checked the web script and it’s returning everything fine to the agent.

Seems to be working again.

I’ll get my coat.
