Kestra task output method - Python boolean not rendered properly

[pdondin]

Describe the issue

Came from this #help message : https://kestra-io.slack.com/archives/C03FQKXRK3K/p1733159976009429

Context
I have a python script task that basically ends with :

results = {
    'domain': domain,
    'keywords': keywords,
    'description': description,
    'scraping_successful': scraped_data is not None,
    'scraped_content': scraped_data
}

logger.info(results)
# output data for the next task

Kestra.outputs(results)

And while trying to access {{outputs.scrape_website.vars.results}}, it ended up as NameError: name 'true' is not defined. Did you mean: 'True'

Discussion with @Ben8t ; it looks like it should have been the case.
PS : More code context in the slack thread if needed

I found a quick patch going through a json string instead to pass those parameters.

Kestra.outputs({"results": json.dumps(results)})

And getting the var using :

input = {{ outputs.scrape_website["vars"] }}
data = json.loads(input['results'])
logger.info(data)

Environment

• Kestra Version: latest
• TaskRunner : Process
