ComfyUI Node: Switch JSON

Switch JSON:

The LF_SwitchJSON node is designed to facilitate conditional logic within your AI art workflows by dynamically switching between two JSON values based on a boolean condition. This node is particularly useful when you need to choose between different sets of parameters or configurations depending on specific conditions. By leveraging this node, you can streamline your workflow, making it more adaptable and responsive to varying scenarios. The primary function of the LF_SwitchJSON node is to evaluate a boolean condition and return one of the two provided JSON values accordingly, ensuring that your workflow can handle different cases efficiently and effectively.

Switch JSON Input Parameters:

on_true

This parameter accepts a JSON value that will be returned if the boolean condition is true. It is designed to be lazy, meaning it will only be evaluated if the condition is met. This can help optimize performance by avoiding unnecessary computations. The on_true parameter allows you to define the JSON configuration or data that should be used when the condition is satisfied.

on_false

This parameter accepts a JSON value that will be returned if the boolean condition is false. Similar to on_true, it is also lazy and will only be evaluated if the condition is not met. This ensures that only the necessary JSON value is processed, contributing to a more efficient workflow. The on_false parameter allows you to specify the JSON configuration or data to be used when the condition is not satisfied.

boolean

This parameter is a boolean value that determines which JSON value to return. It defaults to false and serves as the condition for switching between the on_true and on_false values. The boolean parameter is crucial as it dictates the flow of your workflow, enabling dynamic decision-making based on the specified condition.

Switch JSON Output Parameters:

JSON

The output of the LF_SwitchJSON node is a JSON value. Depending on the boolean condition, it will either be the on_true or on_false JSON value. This output is essential for continuing your workflow with the appropriate configuration or data, ensuring that subsequent nodes receive the correct input based on the evaluated condition.

Switch JSON Usage Tips:

• Use the boolean parameter to control the flow of your workflow dynamically, allowing for more flexible and adaptable processes.
• Ensure that the on_true and on_false JSON values are well-defined and appropriate for the scenarios they represent to avoid unexpected results.
• Utilize the lazy evaluation feature to optimize performance by only processing the necessary JSON value based on the condition.

Switch JSON Common Errors and Solutions:

"Invalid JSON format"

• Explanation: This error occurs when the provided on_true or on_false value is not a valid JSON.
• Solution: Verify that both on_true and on_false parameters contain properly formatted JSON values.

"Boolean parameter missing"

• Explanation: This error occurs when the boolean parameter is not provided.
• Solution: Ensure that the boolean parameter is included and correctly set to either true or false.

"Unexpected keyword argument"

• Explanation: This error occurs when an unexpected argument is passed to the node.
• Solution: Check the input parameters and ensure that only on_true, on_false, and boolean are provided.

"Node execution failed"

• Explanation: This error occurs when there is an issue during the execution of the node.
• Solution: Review the input parameters and ensure they are correctly set. Check for any issues in the workflow that might affect the node's execution.
