The linked service was deleted, this significantly hinders our ability to provide support.

But, this is likely what you need to read to overcome that error -

https://docs.railway.com/reference/build-and-start-commands#start-command

Specifically the section about wrapping your start command in a shell.

Hi Thank you so much. I removed the dockerfile and update that stat comman in setting but the app still crashes. It works perfectly fine in my localhost. Only when i comppleted working on it i uploaded it in github. I am not sure what the issue is whie deployment.

Since the original project was deleted, please provide a link to a new project.

The setup lists python, yet the start command uses npm? can you help me to understand this?

Also, What python version are you using locally?

I am able to run the app now. However i am seeing issue with the postgresql. I have functionality to upload the data and it is stored in the database by the functions. Hoewver i am seeing this error ('danger', 'Error saving data to ratingmatrix: connection to server at "localhost" (::1), port 5432 failed: Connection refused\n\tIs the server running on that host and accepting TCP/IP connections?\nconnection to server at "localhost" (127.0.0.1), port 5432 failed: Connection refused\n\tIs the server running on that host and accepting TCP/IP connections?\n') I checked if my code still has links with localhost but i dont see it in my config.py or app.py or .env. Could you please help me with this? thank you

The database on Railway is not accessable via localhost, you need to connect to the database that you are hosting on Railway.
