Error message

cannot read "${target.displayPath}": ${info.size} bytes exceeds the ${maxBytes}-byte limit

What it means

Error "cannot read "${target.displayPath}": ${info.size} bytes exceeds the ${maxBytes}-byte limit" thrown in deepseek-ai/deepseek-harness.

Source

Thrown at packages/fs/fs-local/src/fsio.ts:404

 * Read a whole regular file as raw bytes with no decoding or binary rejection.
 * `maxBytes` bounds the complete content: the stat size short-circuits an
 * oversized file before any content I/O, and the stream reads at most one byte
 * beyond the cap so a file growing after stat cannot cause unbounded buffering.
 * @param target - the resolved file to read.
 * @param signal - aborts the read (`FS_ABORTED`).
 * @param maxBytes - inclusive byte cap on the complete content (`FS_TOO_LARGE`).
 * @param internals - test seam for a deterministic post-stat growth race.
 * @returns the full raw content, at most `maxBytes` long.
