fatal: could not read Username for 'http://bitbucket.org': No such device or address

[Bhala]

I'm getting this fatal issue and need to know how to resolve it:

My shell script is as follows which works locally but not remotely:

#!/bin/sh
DIR=master
echo "named DIR as $DIR"
if
  [[ -d ""$DIR"" ]]
  echo "if $DIR directory exists"
then
  echo "$DIR exists on your filesystem."
  rm -rf $DIR
  until [ "$(echo "$DIR/"*)" = "$DIR/*" ]; do
    sleep 2
  done
  echo "now '$DIR' directory has been removed."
fi
git rm -r $DIR
echo "now '$DIR' directory has been removed from git local repository else erroring
'already exists in the index'."
git submodule add --force https://bitbucket.org/nchteamnch/proto/src/master/

Bitbucket pipeline log:

Cloning into '/opt/atlassian/pipelines/agent/build/master'...fatal: could not read Username for 'https://bitbucket.org': No such device or address

fatal: clone of 'https://bitbucket.org/nchteamnch/proto/src/master/' into submodule path '/opt/atlassian/pipelines/agent/build/master' failed
