Automate Merge request from draft to ready state

When I use gitlab-ci.yml file to create a new merge request and then merge it, MR is created in Draft state and not in ready state. This is blocking me to merge my branches.

autoMergeRequest.sh

[[ $HOST =~ ^https?://[^/]+ ]] && HOST="${BASH_REMATCH[0]}/api/v4/projects/"

# Look which is the default branch
TARGET_BRANCH=`curl --silent "${HOST}${CI_PROJECT_ID}" --header "PRIVATE-TOKEN:${PRIVATE_TOKEN}" | python3 -c "import sys, json; print(json.load(sys.stdin)['default_branch'])"`;

# The description of our new MR, we want to remove the branch after the MR has
# been closed
BODY="{
    \"id\": ${CI_PROJECT_ID},
    \"source_branch\": \"${CI_COMMIT_REF_NAME}\",
    \"target_branch\": \"${TARGET_BRANCH}\",
    \"remove_source_branch\": true,
    \"title\": \"WIP: ${CI_COMMIT_REF_NAME}\",
    \"assignee_id\":\"${GITLAB_USER_ID}\"
}";

# Require a list of all the merge request and take a look if there is already
# one with the same source branch
LISTMR=`curl --silent "${HOST}${CI_PROJECT_ID}/merge_requests?state=opened" --header "PRIVATE-TOKEN:${PRIVATE_TOKEN}"`;
COUNTBRANCHES=`echo ${LISTMR} | grep -o "\"source_branch\":\"${CI_COMMIT_REF_NAME}\"" | wc -l`;

# No MR found, let's create a new one
if [ ${COUNTBRANCHES} -eq "0" ]; then
    curl -X POST "${HOST}${CI_PROJECT_ID}/merge_requests" \
        --header "PRIVATE-TOKEN:${PRIVATE_TOKEN}" \
        --header "Content-Type: application/json" \
        --data "${BODY}";

    echo "Opened a new merge request: WIP: ${CI_COMMIT_REF_NAME} and assigned to you";
    exit;
fi

echo "No new merge request opened";

gitlab-ci.yml

stages:
    - openMr
    - otherStages

openMr:
    before_script: []   # We do not need any setup work, let's remove the global one (if any)
    stage: openMr
    only:
      - /^feature\/*/   # We have a very strict naming convention
    script:
        - HOST=${CI_PROJECT_URL} CI_PROJECT_ID=${CI_PROJECT_ID} CI_COMMIT_REF_NAME=${CI_COMMIT_REF_NAME} GITLAB_USER_ID=${GITLAB_USER_ID} PRIVATE_TOKEN=${PRIVATE_TOKEN} ./utils/autoMergeRequest.sh # The name of the script

This opens a merge request in draft and not ready? How do I change it to ready?
