Python print statements are not displayed in the Deployment Logs

Hello. I used Google Translate to post this, so there may be some strange sentences.

I’m using the Web Service with the CPU Eco Free plan to deploy a Python program, but the message that should be output by the Print statement does not appear in the Deployment Logs column.

In addition, the error message when an exception occurs is displayed as stderr.

Is this a limitation of the Free plan?

Or is my configuration incorrect?

I would appreciate your advice.


There is no limitation on the Free instance for logs. So it is probably an application issue.
