When I execute a workflow inside the n8n Editor on Railway, all nodes show as if they have no data - both the input and output panels appear empty - even though the run was successful.
However, when I go to the Executions tab afterward and open the same run, I can clearly see all the data and results for each node.

This started happening recently — previously, running nodes directly in the Editor displayed data as expected.

Expected Behavior

When I click “Execute workflow” or “Execute node” in the Editor, I should be able to see the live input/output data for each node after execution.

Actual Behavior

• Workflow executes fully and succeeds (verified in Executions tab). (screenshot 1)

• In the Editor, nodes show no input/output data (empty state). (screenshot 2)

• Switching to Executions mode shows the data. (screenshot 3)

Edit

To fix the issue add the following to your Primary variables:

EXECUTIONS_DATA_SAVE_ON_ERROR

→ all

EXECUTIONS_DATA_SAVE_ON_SUCCESS

→ all

EXECUTIONS_DATA_SAVE_MANUAL_EXECUTIONS

→ true

N8N_DEFAULT_BINARY_DATA_MODE

→ filesystem
