What is the issue or error you’re encountering

Worker fails to deploy with confusing error using wrangler I have another server that has deployed fine with a similar configuration.

What are the steps to reproduce the issue?

Deploy a cloudflare worker with a these config using pnpm

tsconfig.json

{
“extends”: “../../tsconfig.json”,
“compilerOptions”: {
“target”: “ESNext”,
“module”: “ESNext”,
“lib”: [
“ESNext”
],
“moduleResolution”: “bundler”,
“types”: [“@cloudflare/workers-types”]
},
“include”: [“**/*.ts”]
}

wrangler.json

{
“$schema”: “../../node_modules/wrangler/config-schema.json”,
“name”: “tasks”,
“main”: “index.ts”,
“compatibility_date”: “2025-04-05”,
“dev”: {
“port”: 8081
},
“observability”: {
“enabled”: true
},
“triggers”: {
“crons”: [
“0 8 * * *” // Every day at 8
]
}
}

package.json

{
“name”: “tasks”,
“version”: “1.0.0”,
“private”: true,
“scripts”: {
“dev”: “wrangler dev --test-scheduled --show-interactive-dev-session=false --inspector-port=0”,
“push”: “wrangler deploy”,
“wrangler”: “wrangler”
},
“devDependencies”: {
“@cloudflare/workers-types”: “^4.20250405.0”,
“wrangler”: “^4.10.0”
},
“dependencies”: {
“@localpackage/api”: “workspace:^”
}
}

ive received the same error

So I think I may have found a way to fix this. it looks like when the cloudflare builder runs the install command it runs it in the root pacakge so ends up installing everything. So instead:

• Override the builder so it doesn’t run the install dependencies command itself. To do this, add SKIP_DEPENDENCY_INSTALL=true as a build environment variable to the worker. This can be done in setting or when creating it for the first time.
• Set the build command for the worker to whatever your preferred dependency install command is for me it was just pnpm install.

The error would not come up on a rebuild for me a lot of the time if I triggered this from the dashboard but when pushing new code to the repo branch and triggering a new build that way it would fail consistently with this error.

Hopefully, this works for you as well.
