In the Integration log record, on clicking the Flow Run URL field, the following error message is displayed for the flow:

“Unable to process template language expressions in action '<Action Step Name>' inputs at line '1' and column '1965': 'The template language expression <expression> cannot be evaluated because array index '0' cannot be selected from empty array. Please see https://aka.ms/logicexpressions for usage details.'”

Cause

This error can occur due to one of the following causes:

  1. A picklist mapping is not present.
  2. The record has a lookup value for which data has not been integrated.

Resolution

  • If a picklist mapping is not present, create a picklist mapping. For more information, see Adding a New Picklist Value.

  • If the data for the lookup field has not be integrated, import the required data into Anthology Reach.

    For example, in a Contact record in Anthology Reach, if the Program field has a program which is not integrated, the Program must be imported into Reach.
