@qdm12 commented on GitHub (Oct 2, 2021):

Make sure you have bind mounted the file correctly. Usually unexpected end of JSON input means it's an empty file or there is a missing bracket somewhere. The JSON you sent looks correct though, maybe try with https://jsonlint.com/ to be sure.

Also maybe the problem comes from Windows line endings \r\n in the file? 🤔 (probably not, but maybe)
