I'm in Japan. Every time I try to register a new Genmini model API key, I get an “Internal Server Error” and can't register it. I also can't delete or change the currently registered Genmini API key. Has anyone else experienced this?

This error is most likely caused by a recent change in how Dify stores Gemini API credentials. The backend now expects the provider_name field to be langgenius/gemini/google instead of the old langgenius/google/google. If your database still has Gemini credentials with the old value, the backend can't find or update them, which blocks registration, deletion, and modification of Gemini API keys and triggers internal server errors. This is not region-specific and is unrelated to being in Japan (details & fix).

To fix it:

1. Run the migration script PluginDataMigration in api/services/plugin/data_migration.py to update all relevant tables to the new provider name.
2. Restart all backend services to clear credential caches.
3. Try registering, deleting, or updating the Gemini API key again.

If you’re registering a Gemini model that’s deprecated or not supported (like gemini-pro), you’ll also get errors. Use a supported model name such as gemini-1.5-pro-latest, gemini-2.0-flash, or gemini-1.5-flash, and make sure your Gemini plugin is up to date (model support info).

If you still see errors, check that your privkeys directory and SECRET_KEY are intact and haven’t changed, as mismatches here can break credential decryption (privkeys info).

If the problem persists after these steps, collect backend error logs for further diagnosis.

To reply, just mention @dosu.

I use the SaaS version of Dify. Not the community version.
