Flow designer errors

The document defines the errors that are encountered during a flow.

Introduction

During flow orchestration or execution, it's typical to encounter a config, system, or similar errors. Errors can originate while the flow is designed (management errors), or for that matter when the flow is in action (runtime errors).

Flow management error refers to the error that is encountered during a new flow creation, importing an existing flow or publishing the flow. A user cannot publish a flow until all errors are resolved.

Flow runtime error refers to the error that is encountered during flow execution, or resuming it from any task or decision point configured in the flow. If there is unrecoverable error, user is redirected to the default error page and the instance is ended.

The user is shown a customizable error page when the flow ends with system errors. Refer to the following steps to go to the default error page:

Select User experience > Branding.
Navigate to the workflow folder under the specific theme of interest to locate the error_page.html in the error folder.

Like any other template, the flow instance properties, for example error property can be resolved in the error_page.html through macros. To customize the error_page.html, see Modify flow error pages.

The following table refers to the error codes, and description that a user might encounter while the flow is orchestrated.
