Fixes

Migration

If you're using custom evaluation functions in your monitors, you'll need to update them to the new format:

API Monitors

// Old format
;(async function (statusCode, responseTime, responseDataBase64) {
    const resp = atob(responseDataBase64)
    // Your logic here
})

// New format
;(async function (statusCode, responseTime, responseRaw, modules) {
    // responseRaw is the direct response - no need to decode
    // Access cheerio with modules.cheerio
    // Your logic here
})

TCP/Ping Monitors

// Old format
;(async function (responseDataBase64) {
    let arrayOfPings = JSON.parse(atob(responseDataBase64))
    // Your logic here
})

// New format
;(async function (arrayOfPings) {
    // arrayOfPings is directly available - no need to decode
    // Your logic here
})
