JS7 - Online Demo - Workflow - jdTryCatch

The JS7 - Try / Catch Instruction is used for the error handling in a workflow. If any job runs in the try block and failed due to any reason the catch block will execute otherwise it will skip the catch block. If the catch block will also fail then the order will be considered as failed. The folder 04_ErrorHandling contains the example for the try-catch. The four workflows are available with the different use cases for the try-catch:

The jsTryCatch workflow is used for error handling when the execution of the job in the try block will fail the catch will execute and try to complete the order successfully. If the catch will execute and fail then the order is considered as failed. In the example, if the try block generates an odd no then the catch block will execute and try to create an even number to complete the workflow. If the catch block fails to create an even number, the order will fail and end the execution.
