Changelog

Fixed

• Fixed chart export/import stripping flow node data (selectedOperation, parameterValues for ToolboxFunction nodes; name, value for Constant nodes), which caused Fusion to crash with TypeError: Cannot read properties of undefined (reading 'op') after a Toolkit round-trip.

Summary

• ChartResponse.as_request_resource() was calling the base class implementation which used extra="ignore" when validating the response into a request. This silently dropped any field not declared in Toolkit's FlowData Pydantic model — including selectedOperation, parameterValues (for ToolboxFunction nodes) and name, value (for Constant nodes).
• Fusion reads these fields when rendering charts. After a Toolkit export/import, opening the chart in Fusion caused TypeError: Cannot read properties of undefined (reading 'op') because node.data.selectedOperation was undefined.
• Fix: override as_request_resource() in ChartResponse to dump only the known response-only fields (created_time, last_updated_time, owner_id) explicitly, then validate with extra="allow" so all nested node data is preserved opaquely.

Test plan

• test_chart_response_to_request_preserves_flow_node_data — new regression test verifying that Constant (name, value) and ToolboxFunction (selectedOperation, parameterValues) node data survive the response→request conversion, and that response-only fields are excluded
• All existing TestChartIO tests continue to pass

Code Review

This pull request updates the as_request_resource method in the Chart resource class to serialize the model to JSON while excluding metadata fields (created_time, last_updated_time, and owner_id), and then validate it back into a ChartRequest. This ensures that nested flow node data within the workflow collection is preserved. A unit test has been added to verify this behavior. I have no feedback to provide as there are no review comments.
