Ignore non-mandatory information link prompts [Data type: string] in an TIBCO Spotfire Automation Services job execution when replacing data table with information link.

Ignore non-mandatory information link prompts [Data type: string] in an TIBCO Spotfire Automation Services job execution when replacing data table with information link.

When you try to execute a TIBCO Spotfire Automation Services job which has a few tasks:
Task 1: Open from analysis file from library
Task 2: Replace Data table with Information Link (This Information links has prompts which are not mandatory).
Task 3: Save analysis back to library

You may encounter an error while executing the job:

By default a "null" value was passed by the Automation services Job builder to the web service when executing the job. The job fails because it cannot accept null values. Since data type for the values is String, we can pass a "" [double quotes] instead.

On Task 2: Replace Data table with Information Link (This Information links has prompts which are not mandatory),  select columns and click Edit. Enter "" [double quotes] into List of values(separated by comma) filed and click OK. Now, execute the job and it should succeed.
