I get this error message when receiving a message:

        throw new Error('Evaluation failed: ' + helper_js_1.helper.getExceptionMessage(exceptionDetails));

rror: Evaluation failed: TypeError: Cannot read properties of undefined (reading 'features') at Object.window.WWebJS.sendMessage (puppeteer_evaluation_script:92:39) at puppeteer_evaluation_script:10:45 at ExecutionContext._evaluateInternal (/home/bot/bot-whatsapp-main/node_modules/puppeteer/lib/cjs/puppeteer/common/ExecutionContext.js:221:19) at runMicrotasks () at processTicksAndRejections (node:internal/process/task_queues:96:5) at async ExecutionContext.evaluate (/home/bot/bot-whatsapp-main/node_modules/puppeteer/lib/cjs/puppeteer/common/ExecutionContext.js:110:16) at async Client.sendMessage (/home/bot/bot-whatsapp-main/node_modules/whatsapp-web.js/src/Client.js:594:28)
