Using PolymorphicEmbed v4.1.1
I get the error: module PolymorphicEmbed.HTML.Form is not loaded and could not be found
When attempting to import the module as stated in the docs
Has anyone run into and fixed this problem? Is this an issue with the lib or something else in my project?

This sounds like the same issue, but the comments suggest 4.1.1 should have solved it:
https://github.com/mathieuprog/polymorphic_embed/issues/102
Do you have all the modules that this check is expecting?
https://github.com/mathieuprog/polymorphic_embed/blob/68e54e0df69da37bc48bdc160c77579a59adbdb1/lib/polymorphic_embed/html/form.ex#L1-L2

PhoenixHTMLHelpers.Formis not loadedAre those modules not loaded automatically by Phoenix? Where would I import them? In my endpoint?

phoenix_html_helpersis listed as an optional dependency forPolymorphicEmbed, so you’ll need to add it to your project’smix.exsexplicitly.After that, you may need to add it to the
lib/whatever_web.exfile in places whereuse Phoenix.Componenthappens, for instance:https://github.com/fly-apps/live_beats/blob/ac9780472e7019af274110a1cf71250a8d40c986/lib/live_beats_web.ex#L36-L38
