ComfyUI Node: Debug Printer

Debug Printer:

The SeargeDebugPrinter node is designed to help you debug and inspect data streams within the ComfyUI environment. This node is particularly useful for AI artists who need to understand the structure and content of their data at various stages of processing. By enabling this node, you can print detailed information about the data stream, including nested dictionaries, lists, and tuples, in a readable format. This can be invaluable for troubleshooting and ensuring that your data is being processed correctly. The node provides a clear and structured output, making it easier to identify any issues or anomalies in your data.

Debug Printer Input Parameters:

enabled

This parameter is a boolean that determines whether the debug printing is active. When set to True, the node will print the data stream details; when set to False, it will bypass the printing process. The default value is True.

data

This optional parameter represents the data stream you want to inspect. It accepts a data stream of type SRG_DATA_STREAM. If no data is provided, the node will not perform any printing.

prefix

This optional parameter allows you to add a custom prefix to each line of the printed output. It accepts a string value, which can help you identify the source of the debug output when multiple debug printers are used. The default value is an empty string.

Debug Printer Output Parameters:

data

The output parameter data returns the same data stream that was input. This allows you to pass the data stream to subsequent nodes without any modifications, ensuring that the debug printing does not interfere with the data flow.

Debug Printer Usage Tips:

• Enable the enabled parameter only when you need to debug your data stream to avoid unnecessary console output.
• Use the prefix parameter to differentiate between multiple debug outputs, especially in complex workflows.
• Ensure that the data you pass to the data parameter is in the correct format (SRG_DATA_STREAM) to avoid invalid data stream errors.

Debug Printer Common Errors and Solutions:

! invalid data stream !

• Explanation: This error occurs when the data provided to the data parameter is not a dictionary.
• Solution: Ensure that the data you pass is a dictionary or a compatible data stream type.

No output when enabled is False

• Explanation: If the enabled parameter is set to False, the node will not print any debug information.
• Solution: Set the enabled parameter to True to activate the debug printing.

Prefix not applied

• Explanation: If the prefix parameter is not set or is an empty string, no prefix will be added to the printed output.
• Solution: Provide a non-empty string for the prefix parameter to add a custom prefix to the debug output.
