403 Forbidden Error when using JavaScript code in Synthetic Monitor

vuthayak — Thu, 21 Nov 2024 20:00:15 GMT

Hello, as the title suggests, I am running into a "403 - FORBIDDEN" error when executing my synthetic monitor on a JavaScript event. I am using JavaScript to simulate a click on a popup window, as the normal Dynatrace click event does not seem to work, no matter what CSS selectors I provide. I would like to mention that up until a few days ago, the synthetic monitor was working without issues. Additionally, when accessing the site normally, I am able to use the same commands in the Developer Tools console to perform the action with no issues. Does anyone have a solution to this? Thanks.

let btn = document.querySelector("#popup-element") btn.click()

This would be better investigated in a ticket.

Hello @vuthayak

You can solve it through:

Validate the user privileges against the target URL "App", at least active read "viewer" permissions.
Check if the user credentials in credential vaults have been changed from Dynatrace or from the App side.
Regarding the JavaScript, feel free to review: https://community.dynatrace.com/t5/Start-with-Dynatrace/Synthetic-Monitoring-Configuring-RUM-Custom-JavaScript-Settings/td-p/260184
User Access Permissions: https://community.dynatrace.com/t5/Start-with-Dynatrace/Synthetic-Monitoring-Global-Login-Authentication/td-p/259988
Under the configured synthetic Settings > advanced > Ignore specific status code > specify 403 as long as your configurations are accurate.
You also have an option to enable "bypass content security policy"

hoping it helps.

BR,

Peter
