I was attempting to complete configuration of an n8n Workflow Backup imported from an Enterprise template which required various adjustments for the n8n Community Edition. All was going well until and I was using Perplexity w/ DeepSeek R1 to provide assistance until Perplexity had me add a series of Shared Variables. Then after specifically adding the variables “N8NENDPOINTREST” and “N8NENDPOINTREST_OLD”, the system crashed and now Primary fails upon deployment and redeployment. It looks like a communication conflict with connecting to Postgres. I have subsequently updated the Shared Variables in an attempt to correct them, but it appears that the Key: Value pairs register if the value is text, but will not register and resolve the values using Templated values, showing in the main Variables sections in Primary and Postgres when clicking the view icon. Conversely, if I select the Edit field control, the Templated value is displayed.
I am running n8n Community Edition in Queue Mode w/ Webhook processors on the Hobby Plan.
I have a number of n8n workflows I have installed and partially configured and why I was installing to execute a backup workflow as my first executable.
Any assistance is greatly appreciated as I don’t want to have to start over, and the Postgres database itself appears to be okay if I needed to make a backup of the JSON files to reimport with a new instance of n8n should this not be fixable.
Note I am a low code/no guy and am in deep water within Railway, albeit is a very cool hosting app. So step by step guidance would be greatly appreciated.
Thanks in advance for your assistance,

DC
