Yarn offline-mirror: Integrity check failed for "@preact/compat"

Hi! My team is migrating one of the packages in a monorepo to Preact. The monorepo uses yarn offline-mirror. The package that we are migrating uses Next.js.

Reproduction

When we run the following command in terminal:

yarn workspace [package name] add next-plugin-preact preact preact-render-to-string react-ssr-prepass@npm:preact-ssr-prepass react@npm:@preact/compat react-dom@npm:@preact/compat

This is the output:

yarn workspace v1.22.4
yarn add v1.22.4

Command: /usr/local/bin/node
Arguments: /Users/lindsay.bloom/.yarn/lib/cli.js add next-plugin-preact preact preact-render-to-string react-ssr-prepass@npm:preact-ssr-prepass react@npm:@preact/compat react-dom@npm:@preact/compat
Directory: [deleted for privacy purposes]
Output:

If I try running the command a second time, there is no error.

Expected Behavior

There should be no error when running the command the first time.

Actual Behavior

The https://registry.yarnpkg.com/@preact/compat/-/compat-0.0.3.tgz tarball causes build issues as well. The tarball never gets properly added to the npm-packages-offline-cache directory, which then causes build errors in CI/CD when trying to install dependencies.

Here’s a screenshot of the error:

Thanks so much in advance!

This bug isn’t present in 2.x; integrity hashes are now kept for the full package locator.

Closing as this was related to yarn and the way the next-plugin-preact advises installation😅
