Describe the bug
A clear and concise description of what the bug is.
I run the juice shop in my mac book, the version is "12.11", there is a vulnerability in the login page, the field is "email", but the sqlmap cannot find it.

To Reproduce

1. Run the juice shop in the my local mac.
2. Use burp to catch the http post request
   POST /rest/user/login HTTP/1.1
   Host: localhost:3000
   Content-Length: 49
   Accept: application/json, text/plain, /
   User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.183 Safari/537.36
   Content-Type: application/json
   Origin: http://localhost:3000
   Sec-Fetch-Site: same-origin
   Sec-Fetch-Mode: cors
   Sec-Fetch-Dest: empty
   Referer: http://localhost:3000/
   Accept-Encoding: gzip, deflate
   Accept-Language: zh-CN,zh;q=0.9
   Cookie: io=9sCr6Nc12EAyrTFKAAAA; language=en; welcomebanner_status=dismiss; cookieconsent_status=dismiss
   Connection: close

{"email":"test@juiceshop.sh","password":"123456"}

3. Save this request as a text file, called sqli-2.txt
4. Run the sqlmap to scan it.
   python sqlmap.py -r ../test/sqli-2.txt
5. SQLmap throws an error.

Basics of sqlmap. If you are targeting login pages which require OR payloads, you have to use --risk=3

Basics of sqlmap. If you are targeting login pages which require OR payloads, you have to use --risk=3

Does this mean that --risk=3 and --level=5 executes slower because more tests?
I need sqlmap immediately stops and check another line in target file when [WARNING] parameter 'param' does not seem to be injectable arise. Thanks.

[stamparm]

Yes. sqlmap will need to execute more tests.
