We could use some 💛 on our opencollective page –
This error is thrown if a package requires a dependency without adding it in its dependencies or peerDependencies list. In the absence of such a definition, we cannot reliably report the size of the package - since we cannot resolve any information about the package.
In such a case, it's best to report an issue with the package author asking the missing package to be added to its package.json
You can see a detailed stack trace in your devtools console, and open an issue with the relevant details. Working on a more ideal solution for this.
