Hey there! We've found the following might help you get unblocked faster:

• 🧵 Railway always picks Docker as builder even if I specify Railpack
• 🧵 Build Failed: build daemon returned an error < failed to run Build function: Canceled: context canceled >
• 🧵 Feedback: Railpack
• 📚 Railpack

If you find the answer from one of these, please let us know by solving the thread!

Do you have a custom build command or a custom start command in your settings ?
