Log

Write a log message when an Eval Script step executes. The message supports {tag} interpolation using dynamic tag values. Missing tags render "<null>".

Keys

name	key
log	log()

Values

The value is a single string template. Placeholders like {caid} or {vip} are replaced at runtime using the Eval Script tag data.

• {tag} replaces with value in the tag map
• Missing tags render "<null>"
• Only alphanumeric and underscore tag names are interpolated

Usage Example

// Log with interpolation
$ http http://bakery.dev.vtg.paramount.tech/es(no-hockey-in-mexico)/log("{caid} request by {vip}")/star_trek_discovery/S01/E01.m3u8

Notes

• Intended for use inside Eval Scripts only.
• Log output is emitted via the request-scoped logger.
