There are no problems in master. But there is an error if update xlsx:

ERROR in ./node_modules/xlsx/xlsx.mjs 127:88-95
Module not found: Error: Can't resolve 'process/browser' in '/home/fiskus/reps/quilt/catalog/node_modules/xlsx'
Did you mean 'browser.js'?
BREAKING CHANGE: The request 'process/browser' failed to resolve only because it was resolved as fully specified
(probably because the origin is strict EcmaScript Module, e. g. a module with javascript mimetype, a '*.mjs' file, or a '*.js' file where the package.json contains '"type": "module"').
The extension in the request is mandatory for it to be fully specified.
Add the extension to the request.
resolve 'process/browser' in '/home/fiskus/reps/quilt/catalog/node_modules/xlsx'
