It looks like you're trying to capture the value of a Data Attribute. You can do it by referencing the button element's dataset like this:
let mybutton = document.querySelector('button[class="button width-full button--primary"]');
let autoId = mybutton.dataset.automationId;
console.log(autoId);<button class="button width-full button--primary" data-automation-id="signin-submit-btn" data-tl-id="signin-submit-btn" type="submit"><span class="button-wrapper">Sign in</span></button>Reference here: https://developer.mozilla.org/en-US/docs/Learn/HTML/Howto/Use_data_attributes
