Dashboard dies after deploying anything

[sgofferj]

What are the steps to reproduce?

I configured NR to show the dashboard on /:

httpAdminRoot: '/secret',
httpNodeRoot: '/',
ui: { path: "/" },

My dashboard contains only a (blue) worldmap-node at the moment. I did try adding more items to no avail.

• Restart NR
• Access dashboard at /
• Deploy something (even not dashboard-related)
• Try to access dashboard at /

What happens?

After restarting NR, the dashboard correctly appears on /. After deploying anything (even not dashboard-related), the dashboard appears to die and a call to / results in a white page saying "Cannot get /".

What do you expect to happen?

The dashboard should still appear.

My NR originally runs behind Traefik. However, during my debugging attempts, I set up port forwarding directly to the container port 1880. The issue appears also when bypassing the reverse proxy. I also increased the log level to "debug" but didn't see anything in relation to the dashboard in the log.

Forgot: During debugging I tried all offered deployment options (full, partial flow, partial nodes) but the result remains the same.
