Hi @gatici - thank you for creating this issue, the tutorial you referenced - doesn't show the MongoDB charm or how it might be related.

Would you mind updating your issue with the exact comands you used?

I am looking forward to helping you with this ticket and improving MongoDB

Hello @MiaAltieri The documentation is updated after I created the issue. Now, I replaced the link to older one which deploys sdcore bundle simply. ( https://canonical-charmed-5g.readthedocs-hosted.com/en/1.3-beta_a/how-to/deploy_sdcore_standalone/ )
