How to Utilize App Platform to Build Wasp-SaaS Application

Hey all,

I’ve been working with the Wasp community extensively, but no one I’ve been able to get in contact with has hosted with DO before. I personally favor DO and really would like to get my hosting configuration setup.

I’m having issues building and deploying my application. I can build it but it is stuck in the build phase using the commands below in the Build Command.

curl -sSL https://get.wasp-lang.dev/installer.sh | sh
wasp completion
wasp db migrate-dev
wasp start

When running wasp start in the Run Command, it throws the errors below:

[2025-03-12 20:28:05] /layers/heroku_nodejs/profile/profile.d/WEB_CONCURRENCY.sh: line 35: cat: command not found
[2025-03-12 20:28:05] /layers/heroku_nodejs/profile/profile.d/WEB_CONCURRENCY.sh: line 35: / 1048576: syntax error: operand expected (error token is "/ 1048576")

[2025-03-12 20:28:05] /cnb/lifecycle/launcher: line 4: exec: bash: not found

When running wasp start locally it runs fine, and technically runs fine in the build command.

Now, there is documentation for deploying Wasp to a VPS which is different than this. I realize I may need to use wasp build along with defining some different ENV parameters. However before digging deeper into that, I want to get some feedback from the DO community to see if anyone can help me utilize the App Platform as I find it extremely convenient.

I do have a managed PostGre DB setup within the app on Digital Ocean, and that connection is working fine. Any help is appreciated, this has been a frustrating week :D
