# Observations

## 1) Loading hard coded data from query (but no entities) causes Prisma error

I was attempting to return hard coded JSON from a query without any entities defined, but ran into the following issue on `wasp start`:

```
Server: /Users/shayne/dev/wasp/examples/waspleau/.wasp/out/server/node_modules/.prisma/client/index.js:3
Server (stderr):     throw new Error(
Server (stderr):           ^
Server (stderr):
Server (stderr): Error: @prisma/client did not initialize yet. Please run "prisma generate" and try to import it again.
Server (stderr): In case this error is unexpected for you, please report it in https://github.com/prisma/prisma/issues

Server (stderr):     at file:///Users/shayne/dev/wasp/examples/waspleau/.wasp/out/server/src/dbClient.js:11:18

Server (stderr):     at async Object.loadESM (internal/process/esm_loader.js:68:5)
Server (stderr): [nodemon] app crashed - waiting for file changes before starting...
```

Therefore, I assumed I needed to migrate, however...

### Running `wasp db migrate-dev` without any entities defined

```
Database successfully set up!
Copying migrations folder from Wasp to Prisma project...
Done copying migrations folder.
Performing migration...
Prisma schema loaded from ../db/schema.prisma
Datasource "db": SQLite database "dev.db" at "file:./dev.db"

Already in sync, no schema change or pending migration was found.

Running generate... (Use --skip-generate to skip the generators)
Error:
You don't have any models defined in your schema.prisma, so nothing will be generated.
You can define a model like this:

model User {
  id        Int     @id @default(autoincrement())
  username  String  @unique
  name      String?
}

More information in our documentation:
https://pris.ly/d/prisma-schema

Error: Migrate dev failed: Migrate (dev) failed with exit code: 1
```

The fix was to add a dummy migration just to get past the Prisma error.

## 2) Axios version pinning

If you add `axios` as a dependency with a different version (like latest), you get the following error since Wasp uses it too:

```
wasp: Error: Dependency conflict for user npm dependency (axios, ^0.21.1): Version must be set to the exactly the same version as the one wasp is using: ^0.21.1
CallStack (from HasCallStack):
  error, called at src/Generator/WebAppGenerator.hs:73:31 in waspc-0.2.2.2-B3XOTY4be7eFFZyFqJsQfH:Generator.WebAppGenerator
```

The fix was to use the exact same version Wasp uses, as specified by the error message:
```
dependencies {=json
  "axios": "^0.21.1"
json=}

```

## 3) Dockerfile keeps getting overwritten. Any way to add to it? Do we want to use Docker Compose to allow for additional services like Redis?

## 4) Dockerfile python stale/heroku container does not support M1/aarch64 [`heroku container:push` did not work]

### First error: python missing (probably for all architectures, need to confirm)

```

------

 ▸    Error: docker build exited with Error: 1
 ```

 Solution was to change base `python` to `python3`.

### Next errors: Prisma openssl related for M1

To bypass all of that, I had to manually build exclusively for x86 first like so: `docker buildx build --platform linux/amd64 . -t web`

I could then run:
```
docker tag web registry.heroku.com/waspleau/web
docker push registry.heroku.com/waspleau/web
```

Snip to save: ` docker buildx build --platform linux/amd64 . -t web && docker tag web registry.heroku.com/waspleau/web && docker push registry.heroku.com/waspleau/web && heroku container:release --app waspleau web`

## 5) Heroku postgres + prisma issue after changing sqlite to postgres

```

Had to delete and re-add database. Probably when I originally deployed with sqlite there it got into a funky state.

TODO(shayne): try to repro with simple, clean example and create a new Issue if it happens again.

## 6) .env file

Is seems the `.env` file is being copied into ./wasp/build/server? However, do we want to be copying over the `.env` at all? Prob ok given we set ENV on hosting provider.

| Bug captured here: https://github.com/wasp-lang/wasp/issues/413 |
| --------------------------------------------------------------- |

## 7) App loads, but only renders the string "Hello world"

Oh still need frontend deployed. Maybe instead of "Hello world" we note the frontend aspect somehow? Or as Martin noted we just say "I am api-server" or something like that

## Summary

I have created a new issue to track all PR comments and these notes to make sure we do not lose track of them.
