Jira API v2 integration with FastAPI and Next.js yields 422 and XSRF issues. Example:
const result = await fetch('/relay', { method: 'POST' });
hey swiftcoder15, i had similar issues with jira api v2. check if you passing the proper csrf token headers and correct content type. maybe your relay endpoint isnt processing them right. try debugging deeper and see if cors config is off.
I encountered similar issues when integrating Jira API v2 with a mixed tech stack. In my case the 422 errors turned out to be due to mismatch in request body formatting and an oversight in expected headers by the Jira endpoint. Adjusting the header configuration and verifying the request payload format resolved the issue. I recommend carefully cross-checking the API documentation for any nuances with CSRF token handling and content-type details, and considering minimal CORS restrictions during debugging to trace where the request body is altered.
Based on my experience with similar setups, I found that the challenge was often not with the API itself but with how client settings were applied. Meticulous attention to header formats and aligning backend parsing expectations helped rescue my integration. I discovered that ensuring the relay endpoint correctly propagates CSRF tokens and other headers between FastAPI and Next.js made a significant difference. Logging every request step was instrumental in identifying the discrepancy, which turned out to be a subtle configuration detail in the middleware layer. It was a rewarding troubleshooting process.
