This is pretty much descriptive. `json_decode` decodes *JSON*
**string**. You are trying to supply a dictionary. `:echo` is useful
for printing various values, though you can’t distinguish `:echo '{}'`
(string with dictionary representation) and `:echo {}` (actualy
dictionary), `:h job_info()` explicitly states what type it returns if
error message is not enough.
You don’t need to decode anything, you *already* have a dictionary. Do
with it just what you wanted to do with `json_decode()` output, e.g.
index it (`let exitval = job_info(s:dbext_job).exitval`).
// And, BTW, `'single quoted string'` is not a valid JSON. If
`json_decode("'single quoted string'")` happened to work, it would be
a bug. JSON only supports double quotes.
