Overview
After deploying N8N via Heroku one-click, the app crashes with H10 errors attributed to database setup issues. What can be done to fix this?
hey flyingstar, i fixed my h10 by checking the db url/env var – had a typo in it. update the connection string and redeploy. hope it helps!
The H10 error I encountered was often due to misconfigured environment variables. I reviewed my Heroku settings, specifically the database URL and other connection details, and compared them with the application’s expected configuration. In my case, updating the environment variables and redeploying resolved the issue. It also helped to verify that all required add-ons and buildpacks were properly installed. I recommend checking your logs thoroughly for any specific messages and ensuring that your configuration aligns exactly with the application’s requirements.
I encountered a similar issue upon deploying N8N and realized that sometimes the H10 error manifests not only because of incorrect database configuration but also due to how environment variables are handled in startup routines. In my case, the issue was partly due to the application not picking up the correct port allocation from Heroku’s dynamic settings and a mismatch in the expected configuration during the initialization phase. Revisiting my startup script and verifying the environment for both the port and other required parameters resolved the problem. I recommend double-checking these aspects to ensure consistency across the environment variables.
