I am using this command to patch and merge kubernetes resource. But getting error saying ’ Error from server (BadRequest): Invalid JSON Patch ’

```auto
 os.popen("oc patch bmh %s -n openshift-machine-api --type='merge' -p %s" % (node_name, node_file_path))

```

output of this bmh file is

$ oc get bmh -A  
NAMESPACE NAME STATE CONSUMER ONLINE ERROR AGE

I am trying to create a secret using the node name from bmh and then patching it so that it will change the state of nodes.

Not sure if you already solved this, but guessing from the variable name `node_file_path`, maybe its because you are using `-p` instead of `--patch-file` with `-p` one is supposed to provide the patch content, to use a file use the `--patch-file` flag.
