  1. Error Code Guide

Variable

Validation Errors#


VARIABLE_MISSING_OPERATIONS#

The operation list in the Variable node is empty or not configured. Variable operations cannot be performed.
Add one or more operations in the Variable node settings.
Specify the operation list in the operations property of the Variable node.

VARIABLE_MISSING_OPERATION_TYPE#

The operation type (operation) is not specified in the Variable node. You must specify how the variable should be handled, such as set, append, or increment.
Specify the operation property for each operation in the Variable node settings.
Check whether the operation type is entered correctly. Supported operation types include set, append, and increment.

VARIABLE_MISSING_VARIABLE_NAME#

The variable name cannot be found in the Variable node. The variable name required for workflow execution is not configured.
Enter the variable name in the variable property in the Variable node settings.
For variable copy operations, enter the target variable name in the target property.

Processing Errors#


VARIABLE_TYPE_MISMATCH#

The Variable node cannot process the variable because the variable type does not match. For example, an arithmetic operation may have been attempted on a string.
Check the variable value in the Variable node settings.
Check whether the type of the operation you are trying to perform in the Variable node is compatible with the variable value.
If necessary, add a node that converts the variable value to another type.

TYPE_CONVERSION_FAILED#

Type conversion failed while processing the Variable node. Check whether the configured value matches the target type.
In the Variable node settings, check whether the type of the value to be converted is correct.
In the Variable node settings, check whether the target type is compatible with the value.
Check the type of the value passed from the previous node in the workflow and review whether it is being handled correctly in the Variable node.

VARIABLE_INDEX_OUT_OF_BOUNDS#

The Variable node attempted to use an index that is outside the bounds of the array.
Check whether the index you want to use in the Variable node settings is smaller than the size of the array.
Review the structure and size of the data passed to the Variable node in the workflow.

VARIABLE_DIVISION_BY_ZERO#

A division-by-zero error occurred during variable calculation. Check whether the divisor is not 0.
Check whether the divisor is not 0 in the Variable node settings.
Check whether the divisor is being set to 0 in the previous step of the workflow.
Use conditional logic to prevent the divisor from becoming 0.

VARIABLE_PROPERTY_NOT_FOUND#

A required property key could not be found while processing the Variable node. Check whether the variable settings are correct.
Check whether the index and key properties are configured correctly in the Variable node settings.
Check whether the property you are trying to access in the Variable node exists in the target object.
Check whether all required properties are configured for the operation you want to use in the Variable node, such as REMOVE_BY_INDEX, ADD_PROPERTY, or REMOVE_PROPERTY.

VARIABLE_COPY_SOURCE_NOT_FOUND#

The source variable to copy could not be found in the Variable node. Workflow execution failed.
Enter the correct node ID and output key in the source property in the Variable node settings.
Check whether the source node runs and generates the variable value.
Check whether the source variable exists in the shared context.
