- Why: getCookieValues() returns an array, but the old code passed it directly to JSON.parse(), causing parsing failures when reading existing consent - What: Check array length before parsing, and parse only the first element (cookieValues[0]) - Context: Fix applied to both gtm-tag-template.js and gtm-tag-template.tpl

Description
getCookieValues()returns an array of matching cookie values, but the code was passing the entire array directly toJSON.parse(). This caused consent state not to be restored from the cookie on page load.The fix checks the array length and parses only the first element (
cookieValues[0]).No more
Unexpected end of JSON inputerror.
