  -H "@/tmp/headers.txt.G7pBq7" 
  -H "Content-Type:application/json" 
  --data @/cygdrive/ .... /data/e2e_tests/data/exports/schemas/std_nf_dy.json

Additional context

Proposal to repair:

    for var in `ls -d ${PWD}/${1}/*`; do
        canonicalPath=$(realpath "${var}")
        fileContent=`cat ${canonicalPath}`                -- new variable
        curl -v \
            -H "@${HEADERS_FILE}" \
            -H 'Content-Type:application/json' \
            --data "${fileContent}" \                -- usage of variable, no @ used
            "${URL}/api/${2}/importItem"

Release notes:
#2129 - Added new variable to store file content before send by curl command to solved an error in windows.
