Error

Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter when running the pipeline by choosing one of the following options from the When errors occur list under the Views tab:

  • Stop Pipeline Execution: Stops the current pipeline execution if the Snap encounters an error.

  • Discard Error Data and Continue: Ignores the error, discards that record, and continues with the remaining records.

  • Route Error Data to Error View: Routes the error data to an error view without stopping the Snap execution.

Learn more about Error handling in Pipelines.

Snap Settings

  • Expression icon ((blue star)): Indicates the value is an expression (if enabled) or a static value (if disabled). Learn more about Using Expressions in SnapLogic.

  • Suggestion icon ((blue star)): Indicates a list that is dynamically populated based on the configuration.

  • Upload icon ((blue star)): Indicates that you can upload files. Learn more about managing Files.

Snap Execution

Default Value
Example: Validate & Execute

Dropdown list

N/A

Select one of the following three modes in which the Snap executes:

  • Validate & Execute: Performs limited execution of the Snap and generates a data preview during pipeline validation. Subsequently, performs full execution of the Snap (unlimited records) during pipeline runtime.

  • Execute only: Performs full execution of the Snap during pipeline execution without generating preview data.

  • Disabled: Disables the Snap and all Snaps that are downstream from it.

Troubleshooting

Error

Reason

Resolution

Interrupted while waiting for dataWriter

dataWriter is still null

"Pre-load truncation of the target table failed";

The target table may not exist, " + "or a database access error may have occurred when trying to execute the " + "TRUNCATE statement";

Verify your database credentials and ensure the target table exists, then try again.

Unable to determine target table " + "column names";

Examples

Excluding Fields from the Input Data Stream

e can exclude the unrequired fields from the input data stream by omitting them in the Input schema fieldset. This example demonstrates how we can use the <Snap Name> to achieve this result:
