Use crowd-textract-analyze-document with start_human_loop

I'm trying to use the crowd-textract-analyze-document widget on a custom task with sagemaker.

The problem is call the human loop from "start_human_loop" function not from analyze_document.

The human loop tasks is not rendered, the error can be reproduced using "render_ui_template" function

response = sagemaker_client.render_ui_template( UiTemplate={"Content": template_content}, Task={"Input": input_json}, RoleArn=role, )

I'm using the default template from the documentation. https://docs.aws.amazon.com/sagemaker/latest/dg/a2i-crowd-textract-detection.html With the minimal ranges to read the data from task.input, so I assume than the error is on the input data.

The error raised is

crowd-html-elements-without-ce-polyfill.js:689 Uncaught TypeError: Cannot read properties of undefined (reading 'text')

The entire json used is this one that includes the "text" attribute, so I don't have any idea of why means the error:
