Swarm doesn't start - I messed up somehow #326

Closed dormant closed 3 years ago

dormant commented 3 years ago

I have been editing SwarmMetadata.config and now swarm will not start. This is on MacOS Big Sur.

I must have messed up, but I can't work out where. I tried using the unedited backup of SwarmMetadata.config, but swarm still doesn't start.

Any advice would be welcome.

Here's the output:

Can you please attach your SwarmMetadata.config so I can take a look?

The problem was the layout used in Swarm config did not exist. I added code to handle such errors in the future.
