Why Does Parsing Jinja Template Format in the Personalization Preview Fail?

Resolve the Jinja template parsing error in MoEngage personalization preview. Usually caused by string operators on integers or incorrect quote usage.

Problem

When attempting to use the personalization preview with an incorrect Jinja template format, the following error is displayed:

Error in parsing jinja template format. Error expected token ’,’, got ‘integer’.

Solution

This error occurs for the following reasons:

1. String operators are applied to the integer data type values in the Jinja code.
2. When creating a campaign, a double quotation mark is used instead of two single quotation marks in the Jinja code.
