Bug: Docker Secrets lead to uncaughtException

[DennisGaida]

As soon as you use docker secrets, you will get the following exception:

error:         uncaughtException: Cannot freeze array buffer views with elements                               15:29:21 [7/7167]TypeError: Cannot freeze array buffer views with elements                                                                                                    at Function.freeze (<anonymous>)                                                                                                                         at deepFreeze (/home/hackmd/app/node_modules/deep-freeze/index.js:2:10)                                                                                  at /home/hackmd/app/node_modules/deep-freeze/index.js:9:7                                                                                                at Array.forEach (<anonymous>)                                                                                                                           at deepFreeze (/home/hackmd/app/node_modules/deep-freeze/index.js:4:33)                                                                                  at /home/hackmd/app/node_modules/deep-freeze/index.js:9:7                                                                                                at Array.forEach (<anonymous>)

If you use random secrets, that are not used by https://github.com/hackmdio/codimd/blob/develop/lib/config/dockerSecret.js, there is no exception. If you used a named secret (e.g. imgur_clientid), like in the following example, you get the exception.

  codimd:
    image: hackmdio/hackmd:2.6.1
    container_name: codimd
    [... other container settings ...]
    secrets:
      - source: codimd_imgur_secret
        target: imgur_clientid # when target = "abcef" no exception, but the secret is not used of course
