# Error Logs
**During the use of the app, you may encounter some issues as follows:**
**This is normal, and here are some guidelines**
PERMISSION_DENIED: Request had insufficient authentication scopes
#### Problem Description:
The error you're encountering indicates that the access token used to make the request to the Google Ads API does not have the necessary scopes to perform the action.
#### Solution:
To resolve this issue, ensure that the access token you're using includes the required authentication scopes. You can do this by following these steps:\
\
1\. Disconnect your google ads account:\
\
\
2\. **Reauthorize OAuth Flow:** reauthorize the OAuth flow to request the updated scopes, and obtain a new access token with the correct permissions.\
\
3\. Click Accept scope: **adwords**
 PERMISSION_DENIED: The specified conversion action name already exists
You may encounter errors when creating conversion events
#### Solution:
This error occurs when you already have a conversion event in Google Ads with the same name as the conversion name you're trying to create.\
We create ads using the formula: **TRAKPILOT\_ + event name**.\
For example, if you want to create a purchase event but there is already a conversion event named **TRAKPILOT\_PURCHASE** in Google Ads, the error will be triggered.
Access your Google Ads account, rename the duplicated event, and everything will function normally.
