Steps to reproduce

After update the vue version from 2.7.10 to 2.7.11 the below prop declaration do not work anymore:

props: { btnEditName: { type: String, required: false, default () { return this.$t('ui.common.edit'); }, }, }

Here is the error that I get on the browser:

vendor.js?id=1e442c890616af120be86f4594f164b7:2 TypeError: Cannot read properties of undefined (reading '_t')

I rolledback to the version 2.7.10, and all works fine.

What is expected?

Declare a prop like

props: { btnEditName: { type: String, required: false, default () { return this.$t('ui.common.edit'); }, }, }

What is actually happening?

This error:
