work with redirected output?

[vogler]

I have a script which redirects its output to a file.
After that line window-size errors reading 'height'.
Is there a way to circumvent this?

npx -y window-size # works fine
# save all output to file, see https://stackoverflow.com/questions/25833676/redirect-echo-output-in-shell-script-to-logfile
exec > >(tee $data/output/scan.log)
exec 2>&1
npx -y window-size # TypeError: Cannot read properties of undefined (reading 'height')
bash -c 'npx -y window-size; exit 0' # same

/root/.npm/_npx/dbb0fbeae5ae92a5/node_modules/window-size/cli.js:16
  console.log('height: ' + size.height);
                                ^

Ok, one workaround is to prefix ROWS=50 COLUMNS=140 to manually set the size.
