jp not doing the same as the playground

[haanjde]

input:
{"z":{"a":{"b":"c"},"g":{"b":"d"},"h":{"b":"e"},"i":{"b":"f"}}}
expression:
z.*|[?b == `d`]
on the playground returns:
[ { "b": "d" } ]
but on Debian 12.5 jp version 0.2.1 with:
jp --filename z.json --expr-file z.jp
returns:
Error evaluating JMESPath expression: invalid character 'd' looking for beginning of value
with return code 1.

Can confirm. I suspect this is related to handling of literals. The playground (and python implementation) interpret

`1`

as the number 1 and

`a`

as the string "a". jp does not seem to have the automatic string interpretation.

See
