Drizzle Kit with Deno Import Map fails with MODULE_NOT_FOUND error

[itizarsa]

In my Deno app, I have custom import paths defined in deno.json, when I run the drizzle-kit generate command it fails with a MODULE_NOT_FOUND error. How do I solve this?

# deno.json

{
	"nodeModulesDir": "auto",
	"imports": {
		"#database/": "./src/database/",
		"#entity/": "./src/entity/",
		"#exception/": "./src/exception/",
		"#util/": "./src/util/",
		"#decorator/": "./src/decorator/",
		"@types/pg": "npm:@types/pg@^8.11.11",
		"drizzle-kit": "npm:drizzle-kit@^0.30.5",
		"drizzle-orm": "npm:drizzle-orm@^0.41.0",
		"pg": "npm:pg@^8.14.1"
	},
	"tasks": {
		"db:generate": "deno -A npm:drizzle-kit generate --config ./src/database/drizzle.config.ts",
		"db:migrate": "deno -A npm:drizzle-kit migrate --config ./src/database/drizzle.config.ts"
	}
}

# drizzle.config.ts

import { defineConfig } from "drizzle-kit";

export default defineConfig({
	dialect: "postgresql",
	schema: "./src/database/schema.ts",
	out: "./src/database/migrations",
	migrations: { schema: "public" }
});

# schema.ts

import { bigint, pgTable, text } from "drizzle-orm/pg-core";
import { ContextManager } from "#util/context.ts";

export const Token = pgTable("Tokens", {
	id: bigint({ mode: "number" }).generatedAlwaysAsIdentity().primaryKey(),
	createdBy: text()
		.$defaultFn(() => ContextManager.userId)
		.notNull()
});

Hey @itizarsa, I think the issue is in your import. It's basically getting confused because it cannot find a module called '#util/context.ts'.
In schema.ts, you could try replacing
instead of

import { ContextManager } from "#util/context.ts";

by

import { ContextManager } from "#util"; 

😉

@bricefriha If the file I'm importing is at src/util/context.ts, how would modifying the import to #util solves it?
