Problem when setting "Date.prototype._nth = null;" from JS #1005
Comments

UPDATE: you don't need to include that |
|
Is there a way to get the example into the thread itself. Just paste in code for the block of Elm and JS you need. You can write a minimal Elm program like this: main =
Browser.element
{ init = \_ -> (0, Cmd.none)
, view = \_ ->text "hi"
, update = \_ _ -> (0, Cmd.none)
, subscriptions = \_ -> Sub.none
}That way it is easy to see what is going on quickly. Highlight the part that is interesting with comments or placement. Etc. I cannot process big files and repos with build scripts and knowing to click through four links to the "right place" to see the issue. Just trim everything and put it in the thread directly. |

Sure. Index.html: <!DOCTYPE HTML>

Elm.Main.init({node: document.getElementById("elm")});

There is no Line 80 in ad16145 |

Good catch, in addition to the check in |

@k-bx thank you for reporting this. I just ran into the same issue. Do you have a hack for making it work until elm/core is fixed? |
|
@mingan yes, as mentioned, you need to make sure there are no |
|
@k-bx thank you for your reply. I should phrased the question differently. To get Elm to work I added |
|
Oh, I'm not sure about that, it was a long time ago. Probably I just ended up not using Date.js at that time, it was all needed only as a process of migrating from a legacy codebase which had Date.js in it |

This is a copy of elm/compiler#1848 but with an SSCCE this time.
Was getting this error in Chrome specifically:
Repo with SSCCE: https://github.com/k-bx/elm-sscce-null-typeerror
Basically, what makes a difference is an inclusion if that
date.js. I haven't got enough details yet to explain why exactly that is happening though.The text was updated successfully, but these errors were encountered:
