I installed Teamcity 8.1.6 and Octopus Version 2.5.6 with the TeamCity plugin 2.5.6
When I open the build step for Octopus to create a deployment pack, I get the error (see attachment Teamcity Error.png)
I have also attached the stacktrace (stacktrace.txt)
I then tried to download an earlier of the TeamCity Octopus plugin (version 2.4.9) and I still get the same error.
Please could you assist
