Hi @rickbutterfield thank you for the PR 🙌

I have tested the tutorial and in my case it works as it should (with few adjustments to the import files). Based on https://docs.umbraco.com/umbraco-cms/v/14.latest-rc/extending-backoffice/development-flow/vite-package-setup#umbraco-package-declaration we have used the elementName in umbraco-package.json to render the element file as the default one on step 3 of setting up the plugin: https://docs.umbraco.com/umbraco-cms/v/14.latest-rc/tutorials/creating-a-property-editor#setting-up-a-plugin. So in this case it is optional to add the export default MySuggestionsPropertyEditorUIElement; in the element file (check the blue hint note as well)🤔

Checking the discord issue I believe the issue is something else. For example it could be due to the path of rendered element being wrong (it mentions a path of 'https://localhost:44360/App_Plugins/Suggestions/dist/suggestions.js' in the umbraco-package.json file which does not seem correct, as it should be "/App_Plugins/Suggestions/dist/suggestions.js").

Hi @rickbutterfield to speed things up and have our documentation up to date, I have added "export default class" on all articles for the tutorial "creating a property editor" in this commit: 7cd9a42 so am closing this one 👍

Thank you again for the PR #h5YR 🙌
