How to solve `Error creating config for VM: Invalid JSON` in minishift?

Question

minishift start

was issued and openshift started:

Login to server ...
Creating initial project "myproject" ...
Server Information ...
OpenShift server started.

The server is accessible via web console at:
    https://192.168.42.37:8443/console

You are logged in as:
    User:     developer
    Password: <any value>

To login as administrator:
    oc login -u system:admin


-- Exporting of OpenShift images is occuring in background process with pid 32067.

At a certain moment, the laptop ran out of free disk space. Once this issue was solved, an attempt was done to restart the minishift, but all commands return:

Error creating config for VM: Invalid JSON

Attempts to solve the issue

1. It turned out that a minishift process was still running. Killing this process and subsequently run minishift status returned the same issue.
2. sudo systemctl restart libvirtd did not solve the issue
3. @tm1701 suggested minishift delete --clear-cache, but that does not solve the issue either

Answer 1

One option to solve this issue is a suggestion as provided by @AndreasGajdosik, i.e. deleting the .minishift directory.

Once rm -rf ~/.minishift was issued and minishift status was run, the issue has been solved:

user@host$ minishift status
