The 'Populate Word Document' engine provides a configuration option named 'Inline Errors' which controls how errors are reported. The 'Inline Errors' configuration option is set to 'No' by default,
If an error occurs during execution an exception is raised and reported:
The details of the actual error are contained within the body of the output, i.e. the information returned by the Encodian action, see below:
The error in this example states:
"The following error occurred populating the word document provided: An error has been encountered at the end of expression 'companyName>>\r'. Unexpected end of expression."
The error message is stating there is an issue processing the companyName token, for this example an invalid token configuration was passed to generate the error:
Optimizing Error Handling - Solution Building
Whilst building your solution we recommend changing the 'Inline Errors' configuration option to 'Yes', this instructs the population error not to throw an exception but to add the error message to the output document:
Upon processing the same request as the previous example, the flow execution will complete successfully where the error is added to the document itself.
This approach to error handling can help speed up the development process.
Optimizing Error Handling - Disable Retries
Alternatively, you can also simply disable Flow's default retry policy which will automatically execute the same request 8 times before an error is thrown, see below:
This configuration will ensure that your flow execution will fail much more quickly, allowing you to validate any errors via the errors collection returned by the Encodian action.
