Error when using initial-data when communicating through traefik #187
Comments

Hm. Do you run Openslides behind a self configured proxy? Please have a look which request comes in. Maybe your proxy does not forward the correct content-type header. The openslides tool uses GRPC to connect to the server, so the instance expects respective header (https://github.com/OpenSlides/OpenSlides/blob/main/proxy/caddy_base.json#L167). |

the proxy that we use informs about a 502 response by the service. that's what Caddy / the proxy service is telling: {

}it shows that the content-type header is passed. but nonetheless, the issue is caused by the employed reverse proxy traefik, it requires to specify a specific URL scheme for grpc services. here's an imperfect snippet as reference for the services:
proxy:
labels:
traefik.enable: "true"
traefik.http.services.openslides-proxy.loadbalancer.server.port: "8000"
traefik.http.routers.openslides.service: openslides-proxy
traefik.http.routers.openslides.rule: Host(`openslides.example.org`)
traefik.http.services.openslides-manage.loadbalancer.server.port: "8000"
traefik.http.services.openslides-manage.loadbalancer.server.scheme: h2c
traefik.http.routers.openslides-manage.service: openslides-manage
traefik.http.routers.openslides-manage.rule: Host(`openslides.example.org`) && PathPrefix(`/Manage/`)i'd like to keep this issue open until #186 is solved (or not), so that other users can find this information. |

i have a reachable OpenSlides instance, but when i execute the
initial-datasubcommand, i get an error:as a sidenote, the
README.mddoesn't give any hint what the purpose and possible contents of this initial data would be, and hence i really can't assess whether this situation poses a problem.addendum: i seems that this command would at least set the
superadminpassword as i can't login to the instance.The text was updated successfully, but these errors were encountered:
