Often this is because most of the stack trace is the same but one or two lines differ resulting in the creation of multiple issues.
Sentry groups issues together based on the Grouping Algorithms shown here. To see why similar events are being grouped into multiple issues, go into issue A, select the Similar Issues tab, and click on the Diff
button next to issue B.
You can also view the EVENT GROUPING INFORMATION at the bottom of the issue details page.
Make sure Early Adopter is enabled in the organization settings to view the EVENT GROUPING INFORMATION details beta.
To override the current grouping behavior, you have some options:
- To configure this using the SDK, take a look at the SDK Fingerprinting documentation page and the documentation specific to your SDK.
- To configure this in your project settings, please read the Server-side Fingerprinting and Custom Grouping Enhancements documentation to learn more.
