Throw

Important

This article describes alternatives and workarounds to mimic the Throw error handling directive.

Make does not offer the Throw error handling directive. This feature implementation is being analyzed and evaluated.

Alternate solution

To conditionally throw an error you may configure a module to make it optionally purposely fail during its operation. One possibility is to employ JSON > Parse JSON module configured to optionally throw an error (BundleValidationError in this case):

You can then attach one of the error handling directives to the error handling route to:

force the scenario execution to stop and perform the rollback phase: Rollback
force the scenario execution to stop and perform the commit phase: Commit
stop the processing of a route: Ignore
stop the processing of a route and storing it in the queue of incomplete executions: Break

The following example shows the use of the Rollback directive:

Workaround - Using HTTP Module

Usecase - Retry after some time if there is no record found using Break Directive. Usually, this is crucial when your record doesn't update instantly and you would like to process it later on in automation. Using this Break directive could be handy with the lesser complexity of the setup.

Current Barrier - Make does not offer a module that would enable you to easily conditionally generate (throw) errors.

To give you a better understanding here is the current setup without modification: This scenario search in Zendesk if there is no use it won’t throw an error forcefully to search it again you would need to implement a complex procedure by saving the record.

Solution - To conditionally throw an error you may replace the module where you want to throw an error, with an HTTP module then perform the search in a second scenario linking the HTTP module using webhook with a second scenario. If no result found you can customize the module to throw an error

Scenario One -

Replace the Module where you want to throw an error with HTTP > Make a Request module
Configure the URL within the query parameter that you will get from the Custom Webhook module and add an optional query parameter to search for the email
Enable the advanced settings and check the evaluate all the states as errors.
Add a Break handler in that HTTP module and configure the setup to run later.

Scenario 2 -

Setup Webhooks > Custom Webhooks as a trigger and copy the URL use it in the HTTP module as shown in the previous steps.
Here use the Zendesk > Search for a User module use the parameter from the HTTP module to perform a query. Enable Continue the execution of the route even if the module returns no results
Add a Router and create two routes
1. Setup the first filter for Record Exist
2. The second one for Record Doesn’t exist
Consecutively setup the webhook response module
1. If result found - send 200 status along with the required body in JSON format.
2. If no result found - Send 4xx/404 and in the JSON no record found

The following example returning the result - You will notice when the Zendesk module executes the API it doesn’t send any error message but in the action, we’re replicating the error using the HTTP module.
