updateIdentetyProvider - either "RESTEASY003065: Cannot consume content type" or ""error" => "HTTP 404 Not Found""

Hello,

I'm trying to update a Keycloak identity provider, and I'm encountering some issues.
According to keycloak-1_0.php, I tried the following:

        $output = $this->keycloakAdminApi->updateIdentityProvider([
                "realm"         => "myrealm",
                "alias"         => "test",
                "enabled"   => false,
            ]);
        
        dd($output);

However, I'm getting the following error message:
string(43) "RESTEASY003065: Cannot consume content type"

To investigate further, I tried making the request from Postman using the JSON payload {"alias":"test", "enabled":false}, and I received the error message : "errorMessage": "Invalid identity provider id [null]"

I found that the request works fine in Postman by adding the providerId field to the JSON payload:
{"alias":"test","providerId":"oidc","enabled":false}

Based on this observation, I modified my code to include the providerId field:

        $output = $this->keycloakAdminApi->updateIdentityProvider([
                "realm"         => "myrealm",
                "alias"         => "test",
                "providerId"    => "oidc",
                "enabled"   => false,
            ]);
        
        dd($output);

However, I'm now receiving an error message: "error" => "HTTP 404 Not Found"

I noticed that the documentation doesn't mention the providerId field as a required one, but it seems to be necessary for the request to work correctly in Postman. I also attempted making the request with only the providerId field:
{"providerId":"oidc","enabled":false}

But it also resulted in the "error": "HTTP 404 Not Found" since no alias means no way to identify the identity provider.

I'm looking for suggestions or insights on how to fix my problem. Any ideas?

Edit: In order to get my code functioning, I switched to using Guzzle for updating the identity providers. The behavior observed is consistent with Postman: It only works when the providerId is included in the request body.
