Hi, I tried to upload my first template to the n8n creator community, but I always get this message.
Already tried two different browsers but it´s still the same. Any ideas?
Many thanks!
Seems like creators portal has some issues. Since one day has passed, can you check once again?
Hey, thanks for the reply. It´s still not working. I have a self-hosted n8n version, but also signed up for a free cloud version. Might this be the problem?
You can try :
-Trying to clear your browser cache and cookies, as this is a common troubleshooting step for n8n web interface issues Can’t Create or Login to n8n account.
-Ensuring you are logged in with the correct account and that there are no conflicts between your self-hosted and cloud accounts.
Share more info about version and platform.
Creator’s hub has completely different credentials. This shouldn’t be a problem.
I uploaded my recent template 3-4 days ago, at that time it was working well.
Hey everyone,
Our template portal is behind Cloudflare’s WAF (Web Application Firewall). When you upload a workflow, Cloudflare inspects the raw JSON (and the template description) in the request body.
Some strings commonly used in n8n (certain JS template literals, optional chaining, emojis or substrings) may look like attack payloads to a generic WAF. When one of these appears in your n8n nodes, prompts or even sticky notes, Cloudflare blocks the request with a 403 before it reaches n8n.
You can use this simple LLM prompt to debug the workflow:
I’m trying to submit an n8n workflow (JSON attached), but it’s being blocked with a 403 error. The upload goes through Cloudflare, so I suspect a WAF rule is triggering. Please inspect the JSON for anything that might trip a WAF (like template syntax, code patterns or special characters) and suggest minimal, safe edits to fix it.
Hope this helps!
