Hello FME Community,

I’m encountering a puzzling issue with a Jinja2 template that I’m running through the PythonCaller in FME Flow. The template works perfectly fine on my local machine, but when I deploy the same script on FME Flow, I receive the following error:

Python Exception <TemplateSyntaxError>: expected token 'end of print statement', got 'X'

Context:

The Jinja2 template is used to generate a Contract document with placeholders that are populated at runtime. Below is a simplified version of the template:

Contract
1. A Person with these Details

2. Name: {{ tag1 }}
   Postcode: {{ tag2 }}
   Date of Birth: {{ tag3 }}
   E-mailadres: {{ tag4 }}

{% for compensation in compensation%}
located at the* / the*: {{ fee.tag70 }}    
section: {{ fee.tag4 }}    
number(s): {{ fee.tag5 }}
{% endfor %}

Steps Taken:

• Local Testing: The template renders correctly when I run it locally using Python (same Jinja2 template) on my machine.
• FME Flow Execution: When running the same script on FME Flow, it fails with the TemplateSyntaxError mentioned above.
• Data Consistency: I confirmed that all necessary data tags are populated and passed correctly to the template.

Request for Help:

I'm reaching out to see if anyone in the community has encountered a similar issue or might have insights into what could be going wrong. Specifically:

• Has anyone experienced differences in how Jinja2 templates are processed between local Python environments and FME Flow?
• Are there known issues or configuration settings in FME Flow that might cause this behavior?
• Any tips on how to further debug this issue within the FME Flow environment?

Thanks in advance for your help.
