UE4 crash reports are compressed archives that are unpacked during ingestion in Relay. After expansion, the size of the resulting envelope and its file attachments was never checked, which could pass attachments far exceeding the maximum size limits.
Note that the current implementation drops the entire envelope if even a single attachment file exceeds the file size limit. I went with this approach because it is consistent to how the store endpoint behaves, reusing the same function. We may want to reconsider this, since in UE4 this is usually log files, which only have marginal value compared to the actual crash report. I suggest tackling this in a follow-up.
