The code appears to be:

EuPmc.prototype.writeRecord = function (record, eupmc) {
  var json = JSON.stringify(record, null, 2)
  var id = eupmc.getIdentifier(record).id
  mkdirp.sync(id)
  fs.writeFileSync(id + '/eupmc_result.json', json)
}

maybe the id is corrupted or has unusual syntax.

Potential fix is to trap and skip?
