Rebuilt web app and now it won't run on github pages

[DOSull]

ALL A HORRIBLE CONFUSION! Somehow or other I moved the .nojekyll file out of root and into the app folder and that caused github pages to exclude _prefixed files from the deployment. See: https://medium.com/@juliakmdev/learning-that-github-pages-struggles-with-certain-file-names-4d867d499ca9

SO YOU CAN IGNORE THIS THREAD

After rebuilding wasm app am getting NS_ERROR_CORRUPTED_CONTENT and blocked because of a disallowed MIME type (“text/html”) errors.

An earlier version of the app here, built with marimo 0.14.10, works fine: https://dosull.github.io/mapweaver/2025.08.10/

While the new version, built with marimo 0.16.50.17.7, is broken: https://dosull.github.io/mapweaver/app/

Very little changed in the app.py source. The big difference is between the marimo versions I used to build the app.

Has anyone seen a problem like this on recent versions of marimo? The broken version works OK on a local python http.server so it's something to do with deployment / security / ?? which is well outside my expertise.

Any help appreciated.

Hmm. OK so the new version works on another server: https://southosullivan.com/misc/app/ so it must be a github pages configuration issue? Except there aren't really very many configuration options, and of course, the old version still works fine.

So something seems like it's changed between 0.14.10 and 0.16.50.17.7 that is causing the html-wasm output app to break on github pages with the errors shown.

[kelreeeeey]

I just opened both of the links you mentioned in the discord-help,

• https://dosull.github.io/mapweaver/2025.08.10/
• https://southosullivan.com/misc/app/

And they are working just fine now.

[DOSull]

Those are the ones I said are working - the broken one is at https://dosull.github.io/mapweaver/app/

[kelreeeeey]

Oh, my bad. Looking at it rn.

[kelreeeeey]

yeah, nothing shows up

[kelreeeeey]

I'd be happy to help, can you please provide a reproducible steps to build the app?

[kelreeeeey]

I kinda have some issue when i'm using requests lib in wasm mode, tho it was fine in local deployment, I opted to urllib3 after some google search. Nothing much i guess.

After the deployment in Ghubpage I found out that my browser (I'm using Brave) requires me to load unsafe scripts to be able to make requests and fetch data from external API.

---

Here's the WASM marimo app: https://kelreeeeey.github.io/marimo-gh-pages/computational_methods_for_geophysics/USGS_earthquakes.html

The app intended to show some earthquakes' data fetched from the USGS using user inputs to build the query urls

The requests cannot be made if I don't load unsafe scripts and reload the page.

[kelreeeeey]

Idk if it'll hepl You, but there is what I've experienced with marimo, requests lib(idk if requests count) and wasm.

[kelreeeeey]

I think, comparing the two version will help You get some information

0.14.10...0.16.5

[DOSull]

Thanks for putting the time in on this - I'll look into it tomorrow (it's late in NZ...)

[kelreeeeey]

You're welcome! Good night!!

[DOSull]

It can't be requests related since the app doesn't use that library at all. First thing I should do is build with 0.17.7 and see if that fixes the problem.

[DOSull]

I'm still seeing the same issue when I rebuild with 0.17.7 (the version of marimo current today). It is broken on github pages, but works on the other server I linked in the original post.

[DOSull]

Turns out that I somehow or other moved the .nojekyll file out of root and into the app subfolder, which caused github pages to exclude _ prefixed files from the deployment. See https://medium.com/@juliakmdev/learning-that-github-pages-struggles-with-certain-file-names-4d867d499ca9

So... not a marimo issue at all.

Thanks @kelreeeeey for taking the time - sorry for wasting yours.

[kelreeeeey]

Glad to hear that!! All good, no problems!!!
