Error "Invalid query parameter $dis " from feathersjs (nodejs framework)

Question

I am facing an invalid query parameter error from feathersjs back end . i am using react as front end. My request is .

I did not write this code initially. the $includeEc was already there, but that does not create an error. I know $include, $limit are there too and $limit is a feathersjs query.

If I remove $dis, there is no error. I need $dis to validate something on my API.

let data = {
    $include: true,
    $includeEc: true,
    $limit: -1,
    $dis: 91,
  };

let res = await client.service('servicerequest').find({ query: data });

If I remove $dis there is no problem.

for some reason, when i add 3 backticks, the whole code is not shown as code in above post. — TylerKenFleck, Nov 25 '21 at 12:21
You need to put the three backticks on their **own line** - see my edits — marc_s, Nov 25 '21 at 16:32

Custom query parameters prefixed with a $ must be explicitly allowed on your feathers service. This was added in feathers 4 in order to improve the default security profile and prevent unwanted params from being passed into the db adapters.

From your example, $limit is part of the common query interface, while the two $include params are likely pre-configured or otherwise allowed by your DB adapter.
