Hello all,

I’m getting this error in LiveView, even when the referenced html.leex file in the error is empty!

There was a call to RocketshipWeb.Router.Helpers.chat_show_path/3 but then I changed it to RocketshipWeb.Router.Helpers.chat_show_path/4 and the error message stayed. Then I deleted everything in the html.leex file and still the same error message.

Thanks for any help.

UPDATE: The issue was I renamed the html.leex to html.slimleex to use the slime engine before deleting the contents. Somehow it appears the contents from the html.leex template was stuck in memory? Because when I renamed it back to html.leex with no contents the problem went away (the page loaded without error and was empty). But now I can’t get anything to save when the file type is html.slimleex, even though I have another file in the directory with html.slimleex that updates fine…

Any help or thoughts here greatly appreciated.
