Hi,

I am trying to send Proxy-Authorization header as below.

LET proxy_header = {"Proxy-Authorization": ["Basic e40b7d5eff464a4fb51efed2d1a19a24"]}

LET doc = DOCUMENT("https://example.com", { driver: "cdp", headers: proxy_header})

But Ferret is crashing with the following error. What could be the issue?

fatal error: fault

I have tried the following as well. That didn't help either.

LET proxy_header = {"Proxy-Authorization": "Basic e40b7d5eff464a4fb51efed2d1a19a24"}

Hey, that's definitely an unexpected behavior.

Hi there!
I am experiencing some problems with headers, and I was wondering if they could be somehow related to this issue.

I am able to set headers correctly like (omitted some headers for brevity):

LET headers = {
    'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
    'Pragma': 'no-cache',
    'Cookie': 'value...'
}

LET doc = DOCUMENT(url, { headers: headers })

The problems arises when I try to do the same with the CDP driver:

LET doc = DOCUMENT(url, { driver: "cdp", headers: headers })

Leaving the driver as it is and removing the headers from the line above works just fine; the combination of both breaks the execution.

The error I see in the logs is:

net::ERR_INVALID_ARGUMENT: DOCUMENT("my url...", {driver:"cdp",headers:headers}) at 10:10

Thanks in advance, regards

P.S. Having a blast with Ferret so far! I just rewrote a python scraper in ~25 LOC instead of 250+ :)
