Hi,

Thank you for your feedback.

We have reproduced this error, and it seems to be an issue in the vue-i18n source code. We are working on an update to fix this problem, and it will be released as soon as possible.

In the meantime, as a temporary solution, you can manually update the vue-i18n dependency to version 9.2.2 in your package.json file:

"vue-i18n": "9.2.2",
