Steps to reproduce
I installed version V0.02 of vanna.ai (I also tried version V0.01) through the Dify marker. When executing it in the workflow, I received the prompt: "Run failed: Failed to transform tool message: PluginInvokeError: {"args":{},"error_type":"DependencyError","message":"You need to install required dependencies to execute this method, run command: \npip install vanna[postgres]"}". I also tried restarting Dify and installing the Vanna.ai tool in the form of a local installation, but neither of these attempts was effective. Other tools installed in the Dify market did not have this problem.
✔️ Expected Behavior
After filling in the key information correctly, vanna.ai should be able to execute properly without reporting any errors.
❌ Actual Behavior
I received the prompt: "Run failed: Failed to transform tool message: PluginInvokeError: {"args":{},"error_type":"DependencyError","message":"You need to install required dependencies to execute this method, run command: \npip install vanna[postgres]"}"
