VisualizaçõesHow can I resolve a TypeError using old version of ember and ember-light-table?
I have the test project at https://github.com/ericg-ember-questions/test_computed_sort
I setup the project by doing the following:
Node version: v12.18.1 (npm v6.14.5)
- npm install --save-dev ember-cli@3.4
- ./node_modules/.bin/ember new test_computed_sort
- cd test_computed_sort/
- ./node_modules/.bin/ember install ember-light-table@1.13.2
- ./node_modules/.bin/ember generate component test-comp
- ./node_modules/.bin/ember serve
{{test-comp}}
Hello
{{#light-table}}
{{/light-table}}
If I comment out the reference to light-table, no error is generated. However, with it, I see in the console:
media.js:15 Uncaught TypeError: decorator is not a function
at media.js:15:1
at Array.reduce (<anonymous>)
at _applyDecoratedDescriptor (media.js:15:1)
at Module.callback (media.js:240:1)
at Module.exports (loader.js:106:1)
at Module._reify (loader.js:143:1)

at Module.exports (loader.js:104:1)
at requireModule (loader.js:27:1)
at Class._extractDefaultExport (index.js:432:1)
What can I do to resolve this error so I can use ember-light-table with this project?

The error kinda hints at this, but it doesn't really make sense unless you're using modern ember -- but you're using 3.4 (thanks for providing that information!!)
The stack in your error is actually very helpful, and here's how you can figure out what the issue is.
I downloaded your reproduction repo (thanks for providing that! reproductions are immensely helpful in debugging!)
I got the same error you did:
The key piece here is the media.js reference.
Clicking into that we see:
that the compiled version of the ember-responsive/services/media file is using decorators --
you have some version of ember-responsive in your app which has decorators.
I saw in your package.json that you're specifying on alder version:
"ember-responsive": "^4.0.2",
this v4 version of ember-responsive only supports ember 3.13 and higher.
Kinda poking around the ember-responsive github, https://github.com/freshbooks/ember-responsive/blob/v3.0.5/config/ember-try.js
I see that the v3 series of ember-responsive supports back to Ember 2.12 -- definitely before decorators before supported.
So downgrading ember-responsive and restarting the app reveals this error:
"Assertion Failed: [ember-light-table] table must be an instance of Table"
this error is documented here: https://github.com/adopted-ember-addons/ember-light-table/issues/726
so it looks like some APIs usage issue.
If you want help figuring that out, feel free to post another question.
