Vulnerability Alert: Failed to parse some alerts

[Kiblyn11]

What would you like help with?

I think I found a bug

How are you running Renovate?

Mend Renovate hosted app on github.com

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

No response

Please tell us more about your question or problem

In logs I have this reported issue and I don't have any PR opening for security issues while it has been enabled in config and worked fine before.

Logs (if relevant)

Hi there,

Get your discussion fixed faster by creating a minimal reproduction. This means a repository dedicated to reproducing this issue with the minimal dependencies and config possible.

Before we start working on your issue we need to know exactly what's causing the current behavior. A minimal reproduction helps us with this. Discussions without reproductions are less likely to be converted to Issues.

Please follow these steps:

1. Read our guide on creating a minimal reproduction.
2. Go to our minimal reproduction template repository.
3. Select the Use this template button to create a new repository based on the template.
4. Work on the minimal reproduction in your own repository.
5. Fill out the information in your repository's README.md.
6. Add the link to your reproduction to the first post of your Discussion. If you are not the original author, you can post a new comment with the link.

If you need help with running renovate on your minimal reproduction repository, please refer to our Running Renovate guide.
Good luck,

The Renovate team
