unable to parse columns when running inside docker container

[waffel]

When I try to debug my simple spring boot based commandline application in gitlab debug console, I get:

Caused by: java.io.IOException: Unable to parse columns

How can I avoid this error?

Using line 3.26.3 in an "amazoncorretto:21-alpine" docker image.
