import accept from '@hapi/accept'
// Next.JS uses the @hapi/accept package to parse and detect languages. If the accept-language header is malformed
// it throws an error from within Next.JS, which results in a 500 response. This ends up being noisy because we
// track 500s. To counteract this, we'll try to catch the error first and make sure it doesn't happen
export default function catchBadAcceptLanguage (req, res, next) {
try {
accept.language(req.headers['accept-language'])
} catch (e) {
// if there's a problem with parsing 'accept-language', just clear it out.
req.headers['accept-language'] = ''
}
return next()
