Build not working locally when using yarn 4.5.1

[harm-meijer]

After following the instructions

npx @commercetools-frontend/create-mc-app@latest \
  my-new-custom-view-project \
  --application-type custom-view \
  --template starter

I have the following line in my package.json: "packageManager": "[email protected]+sha512.341db9396b6e289fecc30cd7ab3af65060e05ebff4b3b47547b278b9e67b08f485ecd8c79006b405446262142c7a38154445ef7f17c1d5d1de7d90bf9ce7054d"

There are no errors and when I run yarn start it opens a browser but clicking the "Open the Custom View" button shows a popup with the following error: We could not find this Project

"Seach for a project" does not fix the problem as it results in the error nesting in another popup.

I replaced the packageManager in the package.json with "packageManager": "[email protected]" and removed yarn.lock, node_modules and .yarn then run yarn install (installing with yarn 1.22.22) then yarn start it'll open the browser and clicking the "Open the Custom View" button will open the custom view.

I am using:
nvm: 0.39.7
corepack: 0.29.3 (enabled corepack)
yarn: 1.22.22 (because of the added entry in package.json, it would previously default to 4.5.1)
node: v20.18.0

Hey @harm-meijer 👋

I'm not able to reproduce the issue. Can you try "clearing your site data" in Devtools > Application?

[harm-meijer]

I successfully cleared site data and reloaded the page, this will popup "Accept all cookies" and logs in again but still would not open the custom view. Do you have the included "packageManager" entry in the package.json when you initially install the template? I think this may be something from corepack.

[emmenko]

I don't have the packageManager field in package.json

[emmenko]

I have Yarn v1.22. I haven't tried with other Yarn versions.

What errors do you see in the console?

[harm-meijer]

No errors when installing or in building in the terminal

Here are some of the commands I used to reproduce this:

mkdir test
corepack enable
cd test
yarn set version 4.6.0
yarn -v
>> 4.6.0
rm package.json # if there is a package.json the yarn install will fail
yarn -v # should still be yarn 4.6, if not then you can try: corepack prepare [email protected] --activate
>> 4.6.0
npx @commercetools-frontend/create-mc-app@latest \
  my-new-custom-view-project \
  --application-type custom-view \
  --template starter
cd my-new-custom-view-project/
yarn run start

open custom view => could not find this project

Same error with mc custom app:

npx @commercetools-frontend/create-mc-app@latest \
  my-new-custom-application-project \
  --template starter
