Issue in destination url parsing while creating open Gerrit change through Copybara

we want to mirror pending change from source to destination, here is the config we are using to achieve this

core.workflow(
name = "default",
origin = git.origin(
url = "ssh://server/repo.git",
ref = "refs/changes/**/******/*",
),
destination = git.gerrit_destination(
#url = "ssh://**********.git", ssh not working
url = "https://server/r/repo.git",
fetch = "master",
push_to_refs_for = "master",
submit=False,
gerrit_submit=False,
),
mode= "CHANGE_REQUEST",
authoring = authoring.pass_thru("Default email "),
transformations = [
metadata.restore_author("ORIGINAL_AUTHOR", search_all_changes = True),
metadata.expose_label("COPYBARA_INTEGRATE_REVIEW"),
metadata.expose_label("GERRIT_CHANGE_NUMBER"),
]
)

Issue: url for gerrit_destination is not accepting ssh url format, and https format consists of /r or /r/a in the url which is giving error while parsing:
Here is the log:

CAUSED BY: stream is closed

Tried with below solution to avoid the issue:
If we make below changes in the url for finding active changes
1. /r is removed in project path (git/GerritOptions.java : getProject)
2. /r is added for get operation of the change (gerritapi/GerritApi.java)
Then it is able to find the active change.
i.e. https://server/r/changes/?q=hashtag:%22copybara_id_A434D590887C3F125B3383278F978F28_%22%20AND%20project:users/gkulkarni/tools.git%20AND%20status:NEW

Please let us know the correct approach to make https url with /r or /r/a work for gerrit_destination.
