403 Forbidden Error when using JavaScript code in Synthetic Monitor

[vuthayak]

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-...
• User Access Permissions: https://community.dynatrace.com/t5/Start-with-Dynatrace/Synthetic-Monitoring-Global-Login-Authentica...
• 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
