Error: Error: Validation (isSlug) failed for slug

[simhol]

I've received this error on a fresh new project. Just cloned the starter and provided a .env.local file with the API_URL and _KEY to my Ghost instance.

I get the following error in my terminal when running this in my dev environment:

I've changed nothing in the original repo.

@simhol Sorry to hear you are running into issues. This error is coming from your Ghost CMS (there is no isSlug function in this repo).

1. Please comment out API_URL and _KEY in your .env.local: In this case content is fetched from the example Ghost CMS. If this works, you know that the error is caused by your Ghost installation (see Validation (isSlug) failed for slug TryGhost/Ghost#10525) or is related to your specific content.
2. Make sure your Ghost CMS is up-to-date (I am running a v4 instance, but a recent v3 should work too).
3. Try to start with a fresh installation, copy all images over and then export/import 1 post at a time (this is a crude way to isolate problems coming from specific content, but should only be done as a last resort if all other debugging fails). You could also unpublish posts / pages, if you think a post is making trouble.

I also notice that you are building on Windows which is not officially supported (it means you are a bit on your own when it comes to debugging). I recommend using WSL 2 with Ubuntu when building on Windows. However, I don't think this is the issue here.

I will try to unpublish posts or import/export them to identify the malicious content!

[styxlab]

Can you please open a new issue for this error as it looks unrelated?

[styxlab]

I will try to unpublish posts or import/export them to identify the malicious content!

Before doing that, please make sure your Ghost instance is running on a recent version. Please also publish your software versions for OS, Ghost and npm/yarn here. You are getting many errors I have never seen before, so something is fundamentally wrong here.

@simhol: moved the image optimization issue to #76

Closing as not reproducable. If you disagree, please link to a repository with a reproducable example and add some instructions to it.
