Send Content-Type: application/pdf for PDF downloads

[zackkatz]

The download endpoint sets an explicit Content-Type for xlsx and csv but not pdf, so PDF exports are served as PHP's default text/html; charset=UTF-8 under a .pdf filename. The bytes are a valid PDF (%PDF-1.4 … %%EOF) so sniffing browsers cope, but anything trusting the header — proxies, inline previewers, strict HTTP clients — mishandles the file.

One-line addition to the extension switch in AbstractPHPExcelRenderer::renderOutput().

Found during demo QA (Linear MAR-104: "PDF download returns Content-Type: text/html under a .pdf filename").

Warning

Review limit reached

You’ve reached a temporary PR review limit under our Fair Usage Limits Policy.

Your current included review allowance is based on your included PR review attempts over the past 7 days.

Next review available in: 40 minutes

Limit details: You’ve used all 3 included reviews currently available. Your 47 included PR review attempts over the past 7 days set your current allowance at 3 reviews per hour.

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits within each organization.

For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window.

Please refer docs for additional details.
