This is happening since the recent release of ibmcloud cli and there is note mentioned in the release note as well.

But cli should handle the situation properly instead of panic, created IBM-Cloud/ibm-cloud-cli-release#187 to track the issue.

Meanwhile will submit a PR to fix the LANG env variable.
