I would like to know how to delete a message on Azure Storage Queue. Currently I keep getting the following error.

<?xml version="1.0" encoding="utf-8"?><Error><Code>AuthenticationFailed</Code><Message>Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.

x-ms-version:2016-05-31
/gildedhonordev/ghmatchedtickets/messages/<messageid>'.</AuthenticationErrorDetail></Error>

Using this page as guidance, I have created a function that successfully get the queued message. However, the same method keeps failing at the Authorization when I want to delete a message.

Below are my codes:

get_queued_message() {
    DATE_ISO=$(TZ=GMT date "+%a, %d %h %Y %H:%M:%S %Z")
    VERSION="2016-05-31"
    HEADER_RESOURCE="x-ms-date:$DATE_ISOnx-ms-version:$VERSION"
    URL_RESOURCE="/$STORAGE_ACC/$QUEUE_NAME/messages"
    STRING_TO_SIGN="GETnnnnnnnnnnnn$HEADER_RESOURCEn$URL_RESOURCE"

    DECODED_KEY="$(echo -n "$STORAGE_KEY" | base64 -d -w0 | xxd -p -c256)"
    SIGN=$(printf "$STRING_TO_SIGN" | openssl dgst -sha256 -mac HMAC -macopt "hexkey:$DECODED_KEY" -binary | base64 -w0)
    
    RET=$(curl -X GET 
        -H "x-ms-date:$DATE_ISO" 
        -H "x-ms-version:$VERSION" 
        -H "Authorization: SharedKey $STORAGE_ACC:$SIGN" 
        -H "Content-Length:0" 
        "https://$STORAGE_ACC.queue.core.windows.net/$QUEUE_NAME/messages")

    MESSAGE=$(echo "$RET" | grep -oP '<MessageText>K[^<]+')
    MESSAGE_ID=$(echo "$RET" | grep -oP '<MessageId>K[^<]+')
    POP_RECEIPT=$(echo "$RET" | grep -oP '<PopReceipt>K[^<]+')
}

delete_queued_message() {
    DATE_ISO=$(TZ=GMT date "+%a, %d %h %Y %H:%M:%S %Z")
    VERSION="2016-05-31"
    HEADER_RESOURCE="x-ms-date:$DATE_ISOnx-ms-version:$VERSION"
    URL_RESOURCE="/$STORAGE_ACC/$QUEUE_NAME/messages/$MESSAGE_ID?popreceipt=$POP_RECEIPT"
    STRING_TO_SIGN="DELETEnnnnnnnnnnnn$HEADER_RESOURCEn$URL_RESOURCE"

    DECODED_KEY="$(echo -n "$STORAGE_KEY" | base64 -d -w0 | xxd -p -c256)"
    SIGN=$(printf "$STRING_TO_SIGN" | openssl dgst -sha256 -mac HMAC -macopt "hexkey:$DECODED_KEY" -binary | base64 -w0)

    curl -X DELETE 
        -H "x-ms-date:$DATE_ISO" 
        -H "x-ms-version:$VERSION" 
        -H "Authorization: SharedKey $STORAGE_ACC:$SIGN" 
        "https://$STORAGE_ACC.queue.core.windows.net/$QUEUE_NAME/messages/$MESSAGE_ID?popreceipt=$POP_RECEIPT"
}

Any help would be appreciated
