I am encountering an authentication issue when attempting to push code via GitHub Actions, utilizing Composio's OAuth2 for GitHub. The specific error message received is:
buildx failed with: ERROR: failed to build:
failed to solve: failed to push ghcr.io/bioanywhere/mcp-gitlab-mcp-server:main: denied: permission_denied: write_package
Could you please advise on how to resolve this permission denied error, specifically regarding the "write_package" scope, or suggest alternative solutions?

12/02/2025, 2:31 PMthere's a way to auto-link the repository during the build using Docker labels.
bio
12/02/2025, 2:32 PMBy adding the org.opencontainers.image. source label, the package automatically links to the repository with proper permissions.
bio
12/02/2025, 2:32 PMThe github workflow should adds the org.opencontainers. image. source label during the Docker build:
bio
12/02/2025, 2:33 PMlabels:
org.opencontainers.image.source=${{ github.server_url }}/${{ github.repository }}
org.opencontainers.image.description=MCP Server Docker Image org.opencontainers.image.licenses=MIT
