Hello @yoramshai , I believe this is due to the way plugin is trying to reach the backend in your setup.
I suggest checking your ingress.
We will try to replicate the issue and help you out. :)

[duke-b]

@yoramshai
we have detected and hopefully solved the CORS issue in our new release (0.3.1).
If you could let us know if the issue is still present for you, we'll be here to help.

[yoramshai]

Thank you @duke-b
once I will back to it I will update if it solved.

Hi @duke-b this error is still happening, im using the latest version (0.4) and the plugin cant get some data from DevLake.
If works for something the failed API resources launch errors when hit the API directly from postman, this make me to think that inclusive is another bug.

Sample :

Resource : http://localhost:10666/dora/api/metric?type=cfr&aggregation=monthly
Response : Error 1054 (42S22): Unknown column 'repos.name' in 'where clause'

[Saurav0806]

After using the latest backstage opendora plugin, the issue still through the same error

[duke-b]

@miguel258 , from the response error it seems it is having issues with the devlake database in the background.
I have a spare laptop so I will re-run everything fresh on the new environment to try to replicate the issue you are having and post the feedback here shortly.

Hey guys I have Dora deployed in GKE also with devlake as well and I am getting the same CORS error when trying to access Dora from the backstage plugin. Is there any news on this ?
