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

[gayatri-kulkarni1]

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 default@default.com"),
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.
