Unable to access Jira service after restore

Hi,

after restoring a backup of an old gitlab server (gitlab/gitlab-ce:13.0.1-ce.0 with embeded psql) to a new one (gitlab/gitlab-ce:13.0.1-ce.0 with external psql), I'm unable to access Admin/Service Templates/Jira page and Project/Settings/Integrations/JIRA pages.

Error is : 500 Whoops, something went wrong on our end.

Processing by Admin::ServicesController#edit as HTML
  Parameters: {"id"=>"17"}
Completed 500 Internal Server Error in 31ms (ActiveRecord: 4.0ms | Elasticsearch: 0.0ms | Allocations: 9841)
  
ActionView::Template::Error ():

    2: - title = field[:title] || name.humanize
    3: - value = @service.send(name)
    4: - type = field[:type]
    5: - placeholder = field[:placeholder]
    6: - required = field[:required]

Thanks for any help
