Cannot find module './functions/valid'

Hello members!
I’m using Docker for Parse.
In the deployed version of the project on the server, Parse Dashboard throws errors in some situations like adding a new column or adding a new Config row.
It works on my localhost.
This is the error message:

dashboard.bundle.js:45 Error: Cannot find module './functions/valid'
    at n (dashboard.bundle.js:83)
    at dashboard.bundle.js:21
    at Object.get [as valid] (dashboard.bundle.js:21)
    at t.value (dashboard.bundle.js:95)
    at Za (dashboard.bundle.js:45)
    at $a (dashboard.bundle.js:45)

Can you share your Parse Dashboard docker file?

Thanks for your reply.
Sure I can.

Thanks for sharing. I will try to reproduce and let you know then.

We were experiencing the same issue, I have submitted a pull request to the dashboard repo that fixes it here: https://github.com/parse-community/parse-dashboard/pull/1441
