backstage: Could not fetch catalog entities on a all new deployment
Hello,
I’d like to run backstage in my local environment. To do this, I’m following the steps in the gettings-started guide.
Unfortunately, when the app is starting, I have an error :

While I see no errors in the logs of the backend :

N.B : I have the following error in my local environment but I get this error in multiple environments :
- Kubernetes through helm charts deployment
- Yarn deployment on a company VM behind a proxy
- In my local environment in a WSL withtout any proxy.
The reason why I was talking about my local environment is because this is the environment where I made any modifications just the commands below
Steps to reproduce
npx @backstage/create-app ## Create local-backstage app
cd local-backstage && yarn dev
Environment
- Ubuntu 20.04 in WSL 2 on Windows 10
Please let me know if you miss informations
N.B: Backstage seems really great and IMHO could help A LOT of teams growing up 👍

We weren’t getting issue locally ( if you used npx to create initial version,you shouldn’t get into any issue).
When we were deploying docker image with a custom url,we were getting this issue.
We had some cache problem in browser and we changed frontend and backend url to same and then everything worked perfectly fine.
I hope this helps!
