[asterisk-users] CURLOPT(useragent) fails with Set requires an '=' to be a valid assignment

[Jonathan H]

All my other CURLOPT settings like timeout work fine. But this:

same  => n,Set(CURLOPT(useragent)="Mozilla/5.0 (Windows NT 10.0;
Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.41
Safari/537.36")

give the following warning on dialplan reload, with and without quotes
around the user agent. Everything else is fine - perhaps it is the
parenthesis in the user agent?
If so, how do I get round this? I am fairly sure it's a typo at my
end, but I've looked at examples from other people/gists and my usage
looks correct.
It's only the useragent option it chokes on.

    -- Executing [s at setup:3] Set("Local/s at setup-00000006;2",
"CURLOPT(useragent") in new stack
[Dec 14 17:24:30] WARNING[10243][C-00000007]: pbx_variables.c:1140
pbx_builtin_setvar: Set requires an '=' to be a valid assignment.
    -- Executing [s at setup:4] Set("Local/s at setup-00000006;2",
"CURLOPT(conntimeout)=3") in new stack
    -- Executing [s at setup:5] Set("Local/s at setup-00000006;2",
"CURLOPT(dnstimeout)=3") in new stack


NOTE: The reason I'm doing this is because I want Asterisk to give a
different user agent for ControlPlayback function and move on quickly
if the remote file is not available / slow.
If that is not the correct way then please let me know!
