Hi @bizmarker! 👋

It looks like you provided an invalid or unsupported reproduction URL.
Do not use any service other than Codepen, jsFiddle, StackBlitz, Codesandbox, and GitHub.
Make sure the URL you provided is correct and reachable. You can test it by visiting it in a private tab, another device, etc.
Please edit your original post above and provide a valid reproduction URL as explained.

Without a proper reproduction, your issue will have to get closed.

Thank you for your collaboration. 👏

Did you find a solution to this?

I am getting same error when trying to build inside a CI

Cannot use reproduction URL for app extension issue

Cannot provide help with no useful information. You can create a GitHub repo and put a project and AE code there, or at least provide some AE code.

All I can say is that, if your extension is ESM-based, depending on your needs, either don't specify exports or make sure it matches this structure:

quasar/create-quasar/templates/app-extension/ae-ts/BASE/app-extension/_package.json

Lines 17 to 28 in a0e0c76

	"exports": {
	".": {
	"types": "./dist/runtime/index.d.ts",
	"import": "./dist/runtime/index.js"
	},
	"./package.json": "./package.json",
	<% if (preset.prompts) { %>"./dist/prompts": "./dist/prompts.js",<% } %>
	<% if (preset.install) { %>"./dist/install": "./dist/install.js",<% } %>
	<% if (preset.uninstall) { %>"./dist/uninstall": "./dist/uninstall.js",<% } %>

any news?

[yusufkandemir]

@DouglasCalora, there is no info or reproduction. So, unless someone provides one, there won't be any news.
