ComfyUI Node: VIV_Default

VIV_Default:

The VIV_Default node is designed to provide a flexible and straightforward way to handle default values within a subgraph. Its primary purpose is to ensure that a default value is returned when no specific input is provided, thereby maintaining the continuity and robustness of the workflow. This node is particularly useful in scenarios where optional inputs may or may not be available, allowing you to define a fallback value that the system can rely on. By using this node, you can streamline your workflow and avoid potential disruptions caused by missing inputs, ensuring a smoother and more predictable execution of your AI art generation processes.

VIV_Default Input Parameters:

default

The default parameter is a required input that specifies the fallback value to be used when no other input is provided. This parameter ensures that the node always has a value to return, thereby preventing any interruptions in the workflow. The type of this parameter is flexible, allowing you to use any data type that suits your needs. There are no specific minimum, maximum, or default values for this parameter, as it is entirely dependent on the context of your workflow.

inp

The inp parameter is an optional input that, if provided, will override the default value. This allows for dynamic input handling within your workflow, where the node can adapt based on the availability of this input. If inp is not provided, the node will fall back to using the default value. Similar to the default parameter, the type of this parameter is flexible, accommodating any data type required by your workflow. There are no specific minimum, maximum, or default values for this parameter.

VIV_Default Output Parameters:

result

The result parameter is the output of the VIV_Default node. It returns either the inp value if it is provided or the default value if inp is not available. This output ensures that the node always produces a value, thereby maintaining the integrity and flow of the workflow. The type of this output is flexible, matching the type of the input parameters.

VIV_Default Usage Tips:

• Use the default parameter to set a fallback value that ensures your workflow continues smoothly even when optional inputs are not available.
• Leverage the inp parameter to dynamically override the default value when specific inputs are provided, allowing for more flexible and adaptive workflows.
• Ensure that the types of default and inp are compatible to avoid type mismatches and potential errors.

VIV_Default Common Errors and Solutions:

TypeError: incompatible types for default and inp

• Explanation: This error occurs when the types of the default and inp parameters are not compatible.
• Solution: Ensure that both default and inp are of the same or compatible types to avoid this error.

ValueError: missing required parameter default

• Explanation: This error occurs when the default parameter is not provided, which is required for the node to function.
• Solution: Always provide a value for the default parameter to ensure the node operates correctly.

RuntimeError: unexpected error in node execution

• Explanation: This error can occur due to various reasons, such as internal issues within the node or unexpected input values.
• Solution: Check the input values and ensure they are valid. If the issue persists, review the node's configuration and consult the documentation for further troubleshooting steps.
