🔀 refactor(base.py): import Chain from langchain.chains.base instead of importing it from langflow.graph.vertex.types 🔀 refactor(process.py): remove print statement from process_tweaks function 🔀 refactor(process.py): change load_flow_from_json function signature to accept optional tweaks parameter 🔀 refactor(process.py): change return type of build method in Graph class from List[Vertex] to Chain 🧪 test(loading.py): add test case for loading a flow from a JSON file and applying tweaks 🧪 test(loading.py): remove unused import statement The import statement for Chain in base.py is now more explicit and imports it from langchain.chains.base instead of importing it from langflow.graph.vertex.types. The load_flow_from_json function in process.py now accepts either a JSON file path or a JSON object. The print statement in process_tweaks function has been removed. The load_flow_from_json function in process.py now accepts an optional tweaks parameter. The return type of the build method in the Graph class has been changed from List[Vertex] to Chain. A new test case has been added to loading.py to test loading a flow from a JSON file and applying tweaks. An unused import statement has been removed from loading.py.
