tsc failing with llamaindex + Missing tiktoken_bg.wasm when deploy it

[wakeupmh]

I was trying to build my application to run it in an AWS Lambda, however when I run tsc, I get some errors like:

node_modules/llamaindex/dist/type/tools/WikipediaTool.d.ts:1:45 - error TS2307: Cannot find module '@llamaindex/core/llms' or its corresponding type declarations.

1 import type { BaseTool, ToolMetadata } from "@llamaindex/core/llms";
                                              ~~~~~~~~~~~~~~~~~~~~~~~

node_modules/llamaindex/dist/type/types.d.ts:4:35 - error TS2307: Cannot find module '@llamaindex/core/llms' or its corresponding type declarations.

4 import type { ToolMetadata } from "@llamaindex/core/llms";

My tsconfig.json was configured with the following:

{
  "compilerOptions": {
    "target": "ES2020",
    "module": "commonjs",
    "lib": ["es2020", "dom"],
    "declaration": true,
    "strict": true,
    "noImplicitAny": true,
    "strictNullChecks": true,
    "noImplicitThis": true,
    "alwaysStrict": true,
    "noUnusedLocals": false,
    "noUnusedParameters": false,
    "noImplicitReturns": true,
    "noFallthroughCasesInSwitch": false,
    "inlineSourceMap": true,
    "inlineSources": true,
    "experimentalDecorators": true,
    "strictPropertyInitialization": false,
    "outDir": "dist/",
    "rootDirs": ["src"],
    "esModuleInterop": true,
    "typeRoots": ["./node_modules/@types"]
  },
  "exclude": ["node_modules", "cdk.out", "./dist/**/*"]
}

Any idea on how to solve it?

because if I ignore it and deploy it (I am using cdk) I see some errors like that in my Cloudwatch:

2024-07-31T03:28:11.707Z	undefined	ERROR	Uncaught Exception

    ]
}

This is a bundler issue, I think tsc won't work in this case. you will need esbuild or something
