Error message

Package is too large to zip in memory (zip64 archives are not supported).

What it means

createStoredZipArchive accumulates the archive in one buffer and does not support zip64; the total uncompressed size exceeded the 32-bit zip limits, so the package cannot be zipped in memory.

Solutions

  1. Reduce the package size; zip64 archives are not supported for in-memory zipping.
Defensive patterns

Strategy: validation
