Based on the provided documentation, I'd like to help you troubleshoot the issue.

Since you've deleted the old DNS and CNAME records, it's possible that the DNS resolution is not properly set up for your domain. Here are a few things you can check:

DNS Records: Ensure that you have the necessary DNS records in the DNS app of your Cloudflare dashboard. This includes having the correct A, AAAA, and CNAME records for your domain. You can refer to the documentation on DNS Records for more information.
Nameservers: Verify that your domain's nameservers are pointing to Cloudflare's nameservers. You can check this by looking up your domain's nameservers using a tool like digdig or nslookupnslookup. If your nameservers are not pointing to Cloudflare, you'll need to update them at your domain registrar.
DNSSEC: If you had DNSSEC enabled on your domain before adding it to Cloudflare, you'll need to disable it. You can find more information on disabling DNSSEC in the DNSSEC documentation.
CAA Records: Make sure that your CAA records are correctly set up to allow Cloudflare's partner certificate authorities to issue certificates on your behalf. You can refer to the documentation on CAA Records for more information.

To troubleshoot the specific error you're seeing, I'd recommend checking the following:

Error 1001: DNS resolution error: This error indicates a DNS resolution failure preventing access to the requested domain. You can refer to the documentation on Error 1001 for more information.

If you're still having trouble, I'd be happy to help you investigate further. Please provide more details about your setup and the error you're seeing, and I'll do my best to assist you.

Issue resolved! For future reference if anyone else encounter this issue. you need to add both domains (www.yourdomain.com) and (yourdomain.com) in the workers custom domain.
