Can't render .html.erb homepage

[existentialmutt]

Bridgetown Version:
bridgetown 1.0.0.alpha10 "Pearl"

To Reproduce

1. Rename index.html to index.html.erb
2. Start bridgetown and navigate to localhost:4000
3. Expect home page, get a 500 error

I'm experiencing the issue working with the bridgetown repo here: https://github.com/existentialmutt/stimulus_web_components/tree/erb_no_work

Current behavior
navigating to localhost:4000 responds with a 500 error and logs the following to the terminal:

Errno::EISDIR (Is a directory @ io_fread - /home/rafe/code/stimulus_web_components/output/index.html):

Additional context

Jared helped me out on Discord. The solution is to use plain .erb extension because Bridgetown doesn't do .html.erb

Glad to help you out, but I do plan to take a look at this at the very least so we don't spit out a scary Errno::EISDIR (Is a directory @ io_fread error message. Gotta improve the DX here :)

[existentialmutt]

awesome! I agree a better error message would be helpful here.

Does this still happen if you set an explicit permalink on index via frontmatter?
