JSONAPI is not finding nodes claiming "parameter was not converted"

Problem/Motivation

I've got JSONAPI installed with JSONAPI UI in a fairly clean version of 10.0.3. The POST commands work as expected. The GET, though, is generating several different kinds of errors.

The basic URL: /jsonapi/node/article doesn't generate a list of articles but returns an error saying it was looking for a scalar. But when I do add a node UID, I get a slightly different kind of error saying, ""The \u0022entity\u0022 parameter was not converted for the path ." Perhaps I'm getting the UID and the UUIDs confused? Is there an easy way to figure out both of them for a given piece of content?

Thanks for any suggestions for what I might have misconfigured. (And if anyone knows a good way to figure out the full JSON format for all of the possible fields with a PUT, let me know. That's why I started experimenting with the GET.)

Here's the JSON for the first error:

CURL example

Here's an example of what happens with CURL:

curl   --header 'Accept: application/vnd.api+json' \
> http://XXX.com/jsonapi/node/article
{"jsonapi":{"version":"1.0","meta":{"links":{"self":{"href":"http:\/\/jsonapi.org\/format\/1.0\/"}}}},"errors":[{"title":"Internal Server Error","status":"500","detail":"Expected a scalar value as a 2nd argument to \u0022Symfony\\Component\\HttpFoundation\\InputBag::get()\u0022, \u0022array\u0022 given.","links":{"via":{"href":"http:\/\/XXX.com\/jsonapi\/node\/article"},"info":{"href":"http:\/\/www.w3.org\/Protocols\/rfc2616\/rfc2616-sec10.html#sec10.5.1"}}}

And this is an example of looking for a particular article. The regular URL http://XXX.com/node/5 works fine. 

$ curl   --header 'Accept: application/vnd.api+json'  http://XXX.com/jsonapi/node/article/5
{"jsonapi":{"version":"1.0","meta":{"links":{"self":{"href":"http:\/\/jsonapi.org\/format\/1.0\/"}}}},"errors":[{"title":"Not Found","status":"404","detail":"The \u0022entity\u0022 parameter was not converted for the path \u0022\/jsonapi\/node\/article\/{entity}\u0022 (route name: \u0022jsonapi.node--article.individual\u0022)","links":{"via":{"href":"http:\/\/XXX.com\/jsonapi\/node\/article\/5"},"info":{"href":"http:\/\/www.w3.org\/Protocols\/rfc2616\/rfc2616-sec10.html#sec10.4.5"}}}]}

    Can you please add to the issue summary the GET requests you are sending, preferably as CURL commands?

    My GET commands aren't working, but the POSTs are.

    Above I noted that I was having trouble figuring out the JSON schema. This project helped me but only after I did a clean installation on 9.5.3. When I added fields to the article type in the 9.5.3, I could use the explorer to browse the GET response to guess at the right fields to put into the POST. As expected, these fields were unchanged in the version running on 10.0.3.

    BTW, my biggest hassle was figuring out that cross origin scripting was blocking the JSON calls from the explorer. When I turned that off, I was able to get it to work.

    This is the output I got doing a GET request for all articles.

    I think the trouble getting the correct about may be something with your configuration.

    As for getting an individual resource JSONAPI expects the format http://example.com/jsonapi/{entity_type_id}/{bundle_id}/{entity_uuid} where entity_uuid is the uuid not the nid. To get a resource by nid try this format http://example.com/jsonapi/node/article?filter[drupal_internal__nid]=5

    I have same issue, fresh installation of 10.0.3, every get request /jsonapi/node/article or /jsonapi/user/user get same error response (500) with details "Expected a scalar value as a 2nd argument to \"Symfony\\Component\\HttpFoundation\\InputBag::get()\", \"array\" given."

    I found out jsonapi extras module caused this problem, this patch will fix it https://www.drupal.org/project/jsonapi_extras/issues/3331874 🐛 $request->get may no longer return array as of Symfony 6.0 Fixed

    Reopening this issue as I'm getting the same error when trying to access a single node using /jsonapi/node/page/1 end point in a GET request. It actually works when accessing all nodes of one type using /jsonapi/node/page in a GET request. I'm not using jsonapi_extras module or anything else but jsonapi and serialization modules in core. Just created a Basic Page for testing.

    The error I get is the same described in the issue title:

    {"title":"Not Found","status":"404","detail":"The \u0022entity\u0022 parameter was not converted for the path \u0022\/jsonapi\/node\/page\/{entity}\u0022 (route name: \u0022jsonapi.node--page.individual\u0022)"

    I assume the issue is related to the parameter "1" encoding or something but can't see anything in the documentation.

    My bad, I was using the node id instead the uuid as specified in the documentation. Closing again.

    I found "JSON API Defaults" caused this problem. after uninstalling "JSON API Defaults" it worked.
