Execution URL has a wrong domain

Questions
1

I have the following workflow error handler

N8N AUTOMATION HAS AN ERROR<br><br>
<b>Workflow Name:</b> {{ $json.workflow.name }}<br>
<b>Error Message:</b> {{ $json.execution.error.message }}<br>
<b>Execution URL:</b> {{ $json.execution.url }}

However every time I receive an email I see that Execution URL is leads to wrong domain. For example:

Instead of 
https://my-domain.com/workflow/4jHiDiW6tg0H8u6w/executions/146
I see
https://primary-production-30deb.up.railway.app/workflow/4jHiDiW6tg0H8u6w/executions/146

I’ve redeployed multiple times, however I still see wrong domain. In all other places domain is correct.

It’s all in the env variables. Set N8N_EDITOR_BASE_URL in your env variables and give it a value of “https://my-domain.com”. This is per Deployment environment variables | n8n Docs

Then, in your workflow, you can now access this via the handy $env variable. Something like

Execution URL: {{ ${$env.N8N_EDITOR_BASE_URL}/workflow/${$json.workflow.id}/executions/${$json.execution.id} }}

Note that you won’t be able to see this value when typing in. You’ll see something like “[not accessible via UI, please run node]”. This variable only resolves at runtime for safety reasons. But it will run correctly and you’ll get the proper execution url. Let me know if it works.
