Unable to link Jira ticket to Sentry issue

[Dina Osipova]

We are getting 400 Bad request trying to search for Jira ticket in Sentry in order to link them. We have the following integration:  Sentry Self-Hosted <-> Jira cloud. We also checked and assured that all Jira projects are visible in Sentry settings. 

Sentry version is 25.1.0.

Hi and Welcome, 

Given you’re on Sentry self‑hosted 25.1.0 talking to Jira Cloud in September 2025, the most likely cause of 400 Bad Request during “search to link” is Atlassian’s change to the Jira Cloud search APIs.

the legacy search endpoints (/rest/api/2|3/search, /search/id, and /expression/eval). The replacement is the “enhanced JQL” endpoints under /rest/api/3/search/jql with a new paging model and stricter rules. 
Atlassian developer changelog 

Upgrade Sentry self‑hosted to the latest available release (25.7.0 or newer). Newer builds are more likely to include Jira integration updates that use /search/jql correctly. I think its a good way to ask sentry , when and how the have updated,
