Warning using map.field notation (without parentheses)

Your (or one of your lib’s) dependency file_system is doing module.bootstrap instead of module.bootstrap().
This was already fixed, see here so the best you can do is to update the dependency or the lib that is using it.

EDIT: It’s not an error, just a warning.

where the current file code in my phoenix to fix it?

Try this:

mix deps.update file_system

And tell us if it indeed has upgraded the library and if then compilation yielded warnings (or not).

still show the warning Sir

Show us your console output?

Thankyou Sir, it’s Works, I don’t know to solved another error warning, but at this moment it’s solved

Well, looks like this particular warning is now gone.

You can also try individually upgrading the dependencies that have warnings i.e.

mix deps.update tailwind
mix deps.update mint
mix deps.update phoenix_live_dashboard

But be warned, since LiveView is still not 1.0, stuff might break. Better backup and/or make sure that you can revert the project to where it was before running the commands (usually git revert . should work).

Thanks A lot Sir
