EntityOverviewDashboardViewer

[kerenbenzion]

I am trying to use EntityOverviewDashboardViewer in order to view in my component a graph from grafana.
I managed to view the page of grafana after enabling allow_embedding = true in my grafana, but when I try to login to grafana it keeps sending me again to the login page even though the login was successful .

Important things to know:
I tried also to use port-forwarding for grafana and when I used it it worked but when I use the endpoint configured in the ingress it does not work.
Also., I have noticed that when I use the ingress I get reposnse 302 from grafana.
It is only happening when I try to use the backstage plugin. when I use it from browser everything is working as usual
Can you please assist ?

Hi @JulienKleinmann, I didn't find any solution and still use EntityGrafanaDashboardsCard 😢

Hello @KyryloKarpenko,
did some test on an isolated docker environment, seems to work if you have in your env or equivalent in grafana.ini :
GF_SECURITY_ALLOW_EMBEDDING=true
GF_SECURITY_COOKIE_SAMESITE=none
GF_SECURITY_COOKIE_SECURE=true
can you test on your side and confirm ? i used chrome, seems that if you are using edge it might be different settings.
kind regards,

Hi @JulienKleinmann, if I remember correctly, I initially did the same, but in grafana.ini:

        security:
          allow_embedding: true
          cookie_samesite: none
          cookie_secure: true

For me, there was the same problem as it is described in the issue.

@KyryloKarpenko
definitely work on my side..
I guess you can try to align version with what I have, I have read somewhere that some grafana version might have this issue.

chrome version : Version 127.0.6533.89 (Official Build) (64-bit)
grafana version : Grafana v7.3.1 (6668161a88)

grafana config :

seems to be default of the image : docker-hub.pictet.com/grafana/grafana:7.3.1

also find that in my grafana.ini :
[auth.anonymous]
enabled = true

so did not pay to much attention but it actually does not ask me to login in the iframe and i see my dashboard but when i click login i am able to login.

I was having this same issue until I tested in different browsers. We can embed a cross-domain iframe from Grafana and log in using Firefox, but not Chrome.

This led me to my partial solution:
grafana/grafana#25758

This may have to do with the Set-Cookie header containing something other than SameSite=None as reported by Chromium in the screenshot below. I assume Firefox ignores this directive and therefore applies the session token as a cookie which lets us log into Grafana as directed.

In case you can't see my screenshot, here's what my error from Chromium says:

This Set-Cookie header didn't speicfy a "SameSite" attribute and was defaulted to "SameSite=Lax," and was blocked because it came from a cross-site response which was not the response to a top-level navigation. The Set-Cookie had to have been set with "SameSite=None" to enable cross-site usage
