It will also have to be added in https://github.com/solid/vocab/pull/62 and in https://github.com/solid/specification/blob/main/notification-subscription-types.html

For reference, here are our [WIP implementation in Solid-Nextcloud](https://github.com/pdsinterop/solid-nextcloud/pull/85) and [WIP tests in the Solid CRUD tests](https://github.com/solid-contrib/solid-crud-tests/pull/63)

it's not a major change, note that the existing one is Web**Socket**Subscription2021 and the one that seems to be missing (unless we misunderstood) is Web**Hook**Subscription2022. The difference 2021/2022 is just...

In https://github.com/cs3org/cs3apis/pull/159#discussion_r766662560 @wkloucek proposed a 3rd option, namely a full URL. So the options are: 1) domain, e.g. "cernbox.cern.ch" 2) origin, e.g. "https://cernbox.cern.ch" 3) full URL, e.g. "https://cernbox.cern.ch/some/path" I'm OK...

Another urgent one: https://github.com/cs3org/reva/blob/v1.19.0/internal/http/services/ocmd/send.go#L119 - see https://github.com/pondersource/oc-sciencemesh/issues/22

Working on this in the `ocmd-error-messages` branch

Improved error message for the first one: ``` >> ocm-invite-forward -idp cernbox.cern.ch -token asdf error: code=CODE_INTERNAL msg="error forwarding invite:json: error sending post request: Post \"http://127.0.0.1:19001/ocm/invites/accept\": dial tcp 127.0.0.1:19001: connect: connection...

A third one (from https://github.com/sciencemesh/oc-sciencemesh/issues/4): > In addition, note the `OK` response to file `Delete` GRPC call, even though the nextcloud storage driver returned a `HTTP 500` HTML error page...

Fourth one: in the ocm-test-suite setup, when looking up sharees in oc1.docker, I'm seeing a call to `/cs3.gateway.v1beta1.GatewayAPI/FindAcceptedUsers` but I can't see the details of it.

``` >> recycle-purge error: code=CODE_INTERNAL msg="error emptying recycle:Unexpected response code from EFSS API: 500" support_trace="124d5fc6e935886db6dae181b1fae9d1" ```
