Bug: setUrlProcessingMetadata runs too late in the beforeSendEvent hook, after requestDataIntegration has processed the event, causing URLs to be missed.
Severity: CRITICAL | Confidence: 0.95

🔍 Detailed Analysis

The setUrlProcessingMetadata function executes in the beforeSendEvent hook, which occurs after requestDataIntegration.processEvent() has already run. Consequently, when setUrlProcessingMetadata attempts to modify isolationScopeData.sdkProcessingMetadata.normalizedRequest.url, requestDataIntegration has already processed the event and populated event.request, or failed to find the URL. This late modification means server-side transaction events will continue to lack URLs, rendering the intended feature non-functional.

💡 Suggested Fix

Move the URL addition logic to an earlier hook like preprocessEvent, or directly set event.request.url within the beforeSendEvent hook instead of modifying scope metadata.

Location: packages/nextjs/src/common/utils/setUrlProcessingMetadata.ts#L24-L33

Potential issue: The `setUrlProcessingMetadata` function executes in the
`beforeSendEvent` hook, which occurs *after* `requestDataIntegration.processEvent()` has
already run. Consequently, when `setUrlProcessingMetadata` attempts to modify
`isolationScopeData.sdkProcessingMetadata.normalizedRequest.url`,
`requestDataIntegration` has already processed the event and populated `event.request`,
or failed to find the URL. This late modification means server-side transaction events
will continue to lack URLs, rendering the intended feature non-functional.

Well tests pass with the fix and fail without it, so the timing looks correct.

Bug: Transaction Event Request Data Uses Wrong Scope

The function modifies capturedSpanIsolationScope metadata, but the transaction event's request field is populated from capturedSpanScope. Modifications to the isolation scope won't affect the URL included in the event since requestDataIntegration reads from the same scope used to populate the initial request field. Should modify capturedSpanScope instead.

Data is merged from the trace data and the isolation scope, also tests pass so I don't think this is valid.
