Issue while running 'cf' command

[senthilmkumar]

Hi I have latest version of CF CLI 6.13.0-e68ce0f
while running 'cf' command I am getting following error

Aww shucks.

Something completely unexpected happened. This is a bug in cf.

Can you provide more details, like did it happen once or every time you run the command? If you recently upgraded from an older cf version, did the same command work? Does it fail with this error for every app, app manifest configuration and subcommand or only some?
Thanks!

• This issue is happening every time I run 'cf'
• Yes, I did upgrade my cf version today from 6.12.4 to 6.13.0
• I had same problem while using previous version also
• Good part is I have few other cf commands working fine ex : cf orgs, cf login, etc...

Do you have any plugins installed, and if you remove them one by one, can you figure out which one may be impacting this, and let us know which plugin it is and how we can get it to test with?

@senthilmkumar @dkoper Confirmed the bug. To reproduce, modify basic_plugin.go in plugin_examples/ to have a long command name. This is the command name I have used to cause the failure really-long-command-name-loooooooooooooooooooooooooooooooooooooooooog.

go build basic_plugin.go
cf install-plugin basic_plugin
cf

@dkoper recently I have installed BluemixAdminCLI plugin, I uninstalled the plugin and it worked.
cf uninstall-plugin BluemixAdminCLI

Now I don't see the any error when I issue 'cf' command.

But I need to use BluemixAdminCLI plugin for my admin activities. Is there a workaround?

Thanks for your help

[dkoper]

According to https://www.ng.bluemix.net/docs/overview/mngdedicated.html, Bluemix Admin CLI plugin requires cf 6.11.2 or later. Assuming the plugin developer(s) tested their plugin with v6.11.2 before release and found no issues, you could also try this version. Or possibly you could try an older version of the plugin: maybe they introduced a new command recently with a long command name that uncovered this issue. Otherwise you can wait until it is fixed in the cli.
