Research direction

Start with the npm run i18n_compile command and inspect src/i18n/messages, especially the locale files named in the warnings and the dropzone.Dropzone.invalidSizeLessError entry. Verify the translation data for that ID and rerun the compilation; done means the warnings and TypeError no longer occur.

Description

Description

The npm run i18n_compile script, which uses formatjs compile-folder, is failing with a TypeError when attempting to compile the translation messages.

This appears to be caused by an undefined translation message for the ID "dropzone.Dropzone.invalidSizeLessError" across multiple language files. The @formatjs/cli tool is issuing a series of warning messages indicating the validation error before the final crash:
