Hello,

I have a kubernetes cluster (k3s, with amd64 and arm64 machines), and I have deployed a gitea instance (chart=gitea-0.0.3 version=1.17.3, with postgresql and memcached). I want to build multi-arch docker images, so I have installed drone (2.15.0) with the drone-runner-kubernetes (1.0.0-rc.3).

When I try to build multi-arch image with `docker buildx --cache-to=...`, I have a error for cache upload (buildx log):

```auto
{\"errors\":[{\"code\":\"MANIFEST_INVALID\",\"message\":\"\"}]}\n

```

In gitea logs, I have :

```auto
2022/11/09 10:57:05 [636aecd1-2] router: completed PUT /v2/<org>/<project>/manifests/<tag> for 10.42.1.143:51544, 400 Bad Request in 48.4ms @ container/container.go:440(container.UploadManifest)

```

How can I give more info to help fix this problem ?

I have looked inside gitea source code, it seams that the mediatype used by buildkit cache is not recognized by gitea (/routers/api/packages/container/manifest.go func processManifest, returns errManifestInvalid), but request mime type looks good  
There is an other use case of errManifestInvalid, in func processImageManifestIndex.
