TC plug-in/create release: "Unexpected character encountered while parsing value: <."

I’ve just set up TC plug-in for first time on a fairly vanilla set up. I already have my packages being created in TeamCity using NuGet command lines and I can create releases and deploy them manually successfully.

I wanted to automatically create the release and deploy it to a ‘Latest’ environment using the ‘Create Release’ step in TC. This is failing, complaining about an unexpected < character:

Any ideas?

Hi Alex,

Thanks for getting in touch!
Could you change your server from: http://localhost:83/app#/ to http://localhost:83/ and let me know how that goes?

Vanessa

Thanks Vanessa,

That did the trick! Fastest fix I’ve ever had from a forum. Thank you.

FYI: I just blogged about my set-up:
