Thanks for the report @amy-morrill - this is strange behavior indeed! It looks like it's coming from [sheetclip](https://www.npmjs.com/package/sheetclip) - specifically `SheetClip.prototype.parse` here: https://github.com/plotly/dash/blob/e746bdbbac5a3581a6cac7ba0431ef03bf7859b5/components/dash-table/src/dash-table/utils/TableClipboardHelper.ts#L101 Sheetclip is an essentially abandoned package -...

Hmph, no, conda doesn't appear to support extras (to be clear, these aren't optional parts of our dash itself, they're optional dependencies. One [suggested solution](https://stackoverflow.com/questions/43389520/installing-extras-using-conda) is to make a metapackage...

Generally though people are able to use Dash with Flask 2.2 (eg https://github.com/plotly/dash/issues/2177) - so is there something else required to generate this problem, some other pinned dependency?

Nicely done! You've tested locally that this message shows up when you run `pytest` and try to use one of these fixtures without `[testing]` (but `pytest` still works if you...

`from dash import html` is the Dash 2.0 import - and I see that `dash-extensions` does include [`dash~=2.0.0`](https://github.com/thedirtyfew/dash-extensions/blob/f59655278eda1ff92ababdb3204953ae08f954e9/requirements.txt#L1) so it's a bit surprising that you have this with an older...

Thanks for bringing this to our attention @stevej2608 - and nice find @nickmelnikov82! I'd consider your solution a hack though, as we don't want users depending on internals like `_prop_names`...

@emilhe Thanks for pointing out `dash-extensions` - lots of good stuff there! Some overlap with functionality we're already working on (eg flattened callback args https://github.com/plotly/dash/pull/1180) and other things we haven't...

Seems reasonable, @T4rk1n you've worked on typing for `dash.testing` a bit, any thoughts? Will it be possible to have this picked up automatically by VSCode when `dash_duo` is used as...

Oh interesting thanks for the report @loveJasmine! The single quotes are making it through into the string we see in Python when this is run in your shell (so we're...

@loveJasmine I'm not sure what "failed to set up" means, can you say more?
