F5 ASM | Bot Defense | TSPD JavaScript errors

Hi everyone! 

I have an open case at F5 and I got a response that I don't like at all. The case was opened because after activating Bot Defense for a website we started to have several errors in the browser console. These errors all come from the TSPD JavaScript.

The F5 support give me this response: "...caused by the bot profile to test the different browser capabilities"

 

Does anyone who uses bot defense have the same symptom?

 

p.s - If i turn off bot defense the errors disappear. 


Thanks
TP

    The screenshot is too small to read the text clearly. Can you copy and paste the errors as text?

    Seems there are network errors and the injected JavaScript can not fetch resources. Uris starting with /TSPD/ and /TSbd/ must be reachable and ASM must be enabled for this uris. They are handled by ASM. Check the network tab to check if the requested uris are correct.

    It's not correct, the JavaScript is trying to access to http://127.0.0.1...

    "url": "http://127.0.0.1:8888/404",
    "url": "http://127.0.0.1:8888/random_url",
    "url": "http://127.0.0.1:8888/400_random_url_with_numbers_403",
    "url": "http://127.0.0.1:8888/200",
    "url": "http://127.0.0.1:8888/403",
    "url": "http://127.0.0.1:8888/302",

     

    Very weird....
