Docker Apache Extra White Space makes PHP page responded as blank page

Question

We are running docker with php:7.4-apache image. The problem we are facing is ... if there are extra space before <?php or after ?> php script tag, the php page stop working and showing only blank page. The error normally shown is

output is already started at line xx.

It usually cause problem with session read/write operation. We need to remove the white space manually from each php page. Is there any option to ignore the white space for such docker running environment.
