# Cloudflare preview builds wiping secrets

*26 September 2026 · Cloudflare*

Someone on Github marked this issue.
I am appalled at how [@CloudflareDev](https://x.com/cloudflaredev) can sit on this. Why are people okay with their secrets being wiped off every preview build, or nobody is using this GH <> Cloudflare bridge? Maybe I should drop the wrangler version to see if things work.

> For some reason, preview builds on Cloudflare workers are not holding up secrets, even when keep vars is set correctly.
