@challiwill and I just saw a similar error when poking around with the blue-green-deploy plugin while investigating this issue cloudfoundry/cli#889 . Specifically when it makes a call to CliCommandWithoutTerminalOutput() here.

Are there any news / suggested workarounds? This breaks the acceptance tests and possibly our introduction of Diego in our system.

Edit: works fine with cf-cli v0.19.0 https://github.com/cloudfoundry/cli/releases/tag/v6.19.0

[dkoper]

@tyyko Thanks for the extra details. So it's working consistently for you on 6.19.0 and fails consistently for you on 6.20.0 and 6.21.0?

[michaelgrifalconi]

Hello @dkoper , I confirm you it always work for me on 6.19.0 and earlier versions and always fails on 6.20.0 - 6.21.0.

Using older versions of the diego-enabler plugin did not change anything on cf-cli 6.20.0

@Infra-Red @Amit-PivotalLabs

Can you try with our edge binary if it's now working for you?
Download links are near the bottom of this section: https://github.com/cloudfoundry/cli#downloads

[Infra-Red]

@dkoper The same issue with edge binary:

ubuntu@jumpbox:~/tmp$ ./cf -v
cf version 6.21.0+5f06b05-2016-08-07

ubuntu@jumpbox:~/tmp$ ./cf enable-diego dora

Error: unexpected end of JSON input

[dkoper]

This issue is fixed in Diego-Enabler - v.1.2.1. Thanks again for taking the time to report the issue.
