Enter-BcContainer -containerName test to open a PowerShell prompt inside the container

docker logs test to retrieve information about URL's again

Additional information

After the container was created, do the following:

1. Open the web client
2. Go to any page, e.g. a Sales Quote
3. Use the share link at the top of the page -> Copy link

4. Use the resulting link, this will cause the following error 5. If I add `&tenant=default` to the URL, it works. But that should automatically happen for system links generated by the client

Does this happen every time?

Yes

Did this used to work?

No
Internal work item: AB#613503

[Freddy-D4P]

I guess this is not only in containers, but also in multi-tenant on-premises installations, right?

[tfenster]

I guess so too but haven't installed outside of containers in a very long time

[aholstrup1]

As Freddy mentioned this is almost certainly a bug in the product and not in containerhelper. I'll create an internal ticket and route it to the right team

[duiliotacconi]

It probably affects MT environments on-prem. We have one in 23.x that should be about to upgrade in few months and hope this bug will be resolved soon. Please update this thread with the platform build where the issue is resolved.

[aholstrup1]

@duiliotacconi I'll keep an eye out on the internal workitem 👍 But just to set the right expectations; We won't be able to provide any ETAs or status updates through this GitHub issue.

If you have customers experiencing product defects the best thing to do would probably be to go through one of the official support channels: https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/help-and-support#bugs
