solid-form-handler doesn't appear to be written in CJS, but also doesn't appear to be a valid ES module

I have the following error in a astro/solidjs app:

solid-form-handler doesn't appear to be written in CJS, but also doesn't appear to be a valid ES module (i.e. it doesn't have "type": "module" or an .mjs extension for the entry point). Please contact the package author to fix. (x2)
(node:48442) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)
 error   Cannot use import statement outside a module
