Minidumps size limit

[WD32]

I am trying to upload native minidumps to Sentry, but some of them have a size larger than 20 MB. According to the documentation, 20 MB is the size limitation for compressed minidump requests, and the limit for uncompressed dumps is 100 MB. However, when I compress a minidump to a ZIP file and try to upload it, Sentry returns an error message saying "Invalid minidump".

I don't understand how to send compressed minidumps and what the documentation means by 'compressed minidump request'.

What am I doing wrong? Is it possible to upload compressed minidumps?

100M is pretty much a hard limit that we do not want to raise. The 20M limit is meant as the http Transfer-Encoding compression, and is being enforced by relay. I don’t think that limit is flexible either.

To clarify, it is the Content-Encoding encoding header, as documented here: https://develop.sentry.dev/sdk/overview/#request-compression The 20M are the limit for the request body, and the 100M for the decompressed minidump.

I checked back with the team, and neither of these limits will be relaxed anytime soon.
