How to download the delta responses in json format with continuation filter option?

Hello kind people,
I'm trying to find a way to download the delta responses by using the continuation option. Below is the cURL that I use. I can run it successfully and get the result if I choose to download it in the "csv" format. However, when I use the below command line, with data format as "json", I get the "httpStatus: 400 - Bad Request" error. I need to have the data in the json file instead of the csv.

Long story short, I can use the command line below to download the csv file but NOT the json file. Could someone help me?

Works: curl --request POST --url https://myCompany.qualtrics.com/API/v3/surveys/mySurveyID/export-responses --header 'content-type: application/json' --header 'x-api-token: myToken' --data '{"format":"csv","useLabels": true,"continuationToken": "myContinuationTokenFromPreviouslyRun"}' 

Doesn't work: curl --request POST --url https://myCompany.qualtrics.com/API/v3/surveys/mySurveyID/export-responses --header 'content-type: application/json' --header 'x-api-token: myToken' --data '{"format":"json","useLabels": true,"continuationToken": "myContinuationTokenFromPreviouslyRun"}' 

Thank you in advance,
UHutch

useLabels isn't valid with json. From the documentation:

When exporting responses as JSON, not all parameters are meaningful. Consequently, the following parameters are not allowed when starting a JSON or NDJSON export:

Here is my code. Before running it, you need to create a text file to store the continuation token. The header can be like "continuationToken|Timestamp". Feel free to update this code for a better run if needed
surveyID='mySurveyID'
token='myToken'
continuationToken=$(echo $(cat My_Text_File_For_Continuation_Token.txt | tail -n1) | awk 'BEGIN{FS="|"} {print $1}')
status=""
percentComplete=""

# 1. Get progressID:
#progressID=$(curl --request POST --url https://myCompany.qualtrics.com/API/v3/surveys/${surveyID}/export-responses --header 'content-type: application/json' --header 'x-api-token: '${token}'' --data '{"format":"json","allowContinuation": true}' | sed -e "s/^.*progressId\\":\\"//" | cut -d'"' -f1) # run this line when downloading the full dataset and get the continuation token for the next incremental run
progressID=$(curl --request POST --url https://myCompany.qualtrics.com/API/v3/surveys/${surveyID}/export-responses --header 'content-type: application/json' --header 'x-api-token: '${token}'' --data '{"format":"json","continuationToken":"'${continuationToken}'"}' | sed -e "s/^.*progressId\\":\\"//" | cut -d'"' -f1)
echo "progressID = ${progressID}"

while [[ ${status} != "complete" && ${status} != "failed" ]] ; do
status=$(curl --request GET --url https://myCompany.qualtrics.com/API/v3/surveys/${surveyID}/export-responses/$progressID --header 'x-api-token: '${token}'' | sed -e "s/^.*status\\":\\"//" | cut -d'"' -f1)
percentComplete=$(curl --request GET --url https://myCompany.qualtrics.com/API/v3/surveys/${surveyID}/export-responses/$progressID --header 'x-api-token: '${token}'' | sed -e "s/^.*percentComplete\\"://" | cut -d'"' -f1)
echo ${status}: ${percentComplete}
done
fileID=$(curl --request GET --url https://myCompany.qualtrics.com/API/v3/surveys/${surveyID}/export-responses/$progressID --header 'x-api-token: '${token}'' | sed -e "s/^.*fileId\\":\\"//" | cut -d'"' -f1)
echo "fileID = ${fileID}"

continuationToken=$(curl --request GET --url https://myCompany.qualtrics.com/API/v3/surveys/${surveyID}/export-responses/$progressID --header 'x-api-token: '${token}'' | sed -e "s/^.*continuationToken\\":\\"//" | cut -d'"' -f1)
echo "continuationToken = ${continuationToken}"
# append the continuation token to an existing text file
echo ${continuationToken}'|'`date +"%Y%m%d_%H%M%S"` >> My_Text_File_For_Continuation_Token.txt

# 3. Get Zip file:
curl --request GET --url https://myCompany.qualtrics.com/API/v3/surveys/${surveyID}/export-responses/${fileID}/file --header 'x-api-token: '${token}'' --output temp.zip

# 4. Unzip temp.zip file:
unzip temp.zip

# at this point, you get the JSON file
