itauscraper's Issues

No node found for selector

Olá Vini, estou vendo aqui que deve ter mudado o HTML do site do Itau.
Eu gostaria de contribuir atualizando o código para corrigir este erro, olha abaixo:

Error: No node found for selector: #varejo > header > div.container > nav > ul > li > div > div > div:nth-child(1) > ul:nth-child(1) > li:nth-child(2) > a

[Bug] Puppeteer fails to find selector on headless mode

Running the itauscraper script results in a failure at the login step. Puppeteer is unable to locate the selector #agencia, throwing an Error: No node found for selector: #agencia.

Environment:

  • Node.js version: v18.17.1
  • Project version: v1.4.2

Steps to Reproduce:

  1. Clone the repository and navigate to the project directory.
  2. Install dependencies via npm install or yarn install.
  3. Run the script

Observe the error:

/home/deck/Projects/itauscraper/node_modules/puppeteer/lib/cjs/puppeteer/common/assert.js:26
        throw new Error(message);
              ^

Error: No node found for selector: #agencia

    at DOMWorld.type (/home/deck/Projects/itauscraper/node_modules/puppeteer/lib/cjs/puppeteer/common/DOMWorld.js:315:32)
    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)

    at async scraper (/home/deck/Projects/itauscraper/itauscraper.js:199:3)

Additional information

  • Running on non-headless mode, it works as expected. This might be due to Itaú checking for automated tools like Pupeteer, and it seems an user-agent can be used to fix this error.
