vault Error ... unsupported protocol scheme ""

I was brainless enough to get into this situation while using the Vault client binary:

unsupported protocol scheme ""

A better translation would be, "WTF my man, is this even a URI??"

It's probably because of a malformed URI or absent URI getting used in a web request by GoLang's HTTP thingy.

if !isHTTP {
        req.closeBody()
        return nil, &badStringError{"unsupported protocol scheme", scheme}
    }

Here's an example of what I did with it:

namespaccckler[micro-service-metadata-provider !?+]$ vault status
Error checking seal status: Get notsosecure/v1/sys/seal-status: unsupported protocol scheme ""
namespaccckler1[micro-service-metadata-provider !?+]$ export VAULT_ADDR=http://127.0.0.1:8200
namespaccckler[micro-service-metadata-provider !?+]$ vault status

Anyone else run into this sort of bungling?
