handler

The entry point to use for the source code when running the canary. For canaries that use the syn-python-selenium-1.0 runtime or a syn-nodejs.puppeteer runtime earlier than syn-nodejs.puppeteer-3.4, the handler must be specified as <i>fileName</i>.handler. For syn-python-selenium-1.1, syn-nodejs.puppeteer-3.4, and later runtimes, the handler can be specified as <i>fileName</i>.<i>functionName</i> , or you can specify a folder where canary scripts reside as <i>folder</i>/<i>fileName</i>.<i>functionName</i> .
