Local plugin packaging cannot be uploaded, reporting a 400 error

Discussion

Dify deployed purely in an internal network with Docker, after locally packaging a plugin and uploading it, encounters errors, but sometimes succeeds. Signature and file size limits have been adjusted:

FORCE_VERIFYING_SIGNATURE=false
PLUGIN_MAX_PACKAGE_SIZE=524288000
NGINX_CLIENT_MAX_BODY_SIZE=500M

Have you solved it now? I also want to ask how to install plugins offline.
