When the database is too big (~800 subjects), I get this error:

/pasteur/homes/ntraut/local/lib/node_modules/bids-validator/validators/tsv.js:14
var rows = contents.split('\n');
^

TypeError: Cannot read property 'split' of undefined

at FSReqWrap.readFileAfterOpen [as oncomplete] (fs.js:303:13)

This error does not happen in all system environments and is caused by abnormal empty callback returns from fs.readFile. When I reduce the size of the dataset, bids-validator works properly.

I updated all the dependencies to their latest version and now I get this error with large datasets:

/pasteur/homes/ntraut/src/bids-validator/utils/files.js:239
var pathParts = relPath.split('/');

I get this error in all environments I tested when the dataset is big, and I never get the bug when the dataset is small.
