__Host- Cookies are not settable from a script

[joshuawilhelmi]

I have checked the following:

• I have searched existing issues and found nothing related to my issue.

This bug is:

• making Bruno unusable for me
• slowing me down but I'm able to continue working
• annoying
• this feature was working in a previous version but is broken in the current release.

Bruno version

3.1.4

Operating System

macOS 15.6.1

Describe the bug

Bruno ignores cookie set manually when it is prefixed by "__Host".

See the example below

.bru file to reproduce the bug

meta {
name: Fetch bruno website and save __Host cookie
type: http
seq: 10
}

get {
url: https://usebruno.com
body: none
auth: inherit
}

script:post-response {
// This doesn't work
bru.cookies.jar().setCookie('https://usebruno.com', {
key: '__Host-SESSION',
value: '12345',
path: '/',
secure: true,
httpOnly: true
})

// This does
bru.cookies.jar().setCookie('https://usebruno.com', {
key: 'Host-SESSION',
value: '12345',
path: '/',
secure: true,
httpOnly: true
})
}

settings {
encodeUrl: true
timeout: 0
}
