The issue you're experiencing, where environment variables are null when executing a node individually in version 0.10.2, might be related to how the VariablePool class initializes and manages environment variables. When executing nodes individually, it's possible that the environment variables are not being correctly passed or initialized in the VariablePool.

In the Dify codebase, the VariablePool class is responsible for managing environment variables, and it initializes them by accepting them as an optional parameter during its initialization. These variables are then added to the pool for access during node execution ^[1].

To address this issue, you might want to check if the environment variables are being correctly passed to the VariablePool when executing nodes individually. Ensure that the initialization process for the VariablePool includes the necessary environment variables in this context, similar to how they are handled when executing the entire process.
