invalid sharelink gives 500

[tripodsan]

Description
an illegal sharelink returns a 500 with our nice broken 500 page:

StatusCodeError at Function.fromError (/nodejsAction/tsfszb1w/index.js:8779:17) at OneDrive.resolveShareLink (/nodejsAction/tsfszb1w/index.js:7983:37) at processTicksAndRejections (internal/process/task_queues.js:97:5) { statusCode: 400, details: { code: 'invalidRequest', message: 'The sharing token is invalid.', innerError: { date: '2021-03-10T12:39:23', 'request-id': 'd6ca86c4-26d0-4676-b128-913bd085647b', 'client-request-id': 'd6ca86c4-26d0-4676-b128-913bd085647b' } } 

which is a bit hard to understand by a new user. maybe return a text:

500 Internal Server Error

Invalid fstab

Add an x-error header while we are at it.
