exec function stdout length about child_process

[isJaakko]

I called exec in my Sketch Plugin, but the return value cannot be returned completely, it can only return 4060 characters. Can you help me?

Simply put, the return value is truncated.

Could this be related? nodejs/node#19218 I've been having strange issues with stdout truncation in very particular circumstances. Seems that it's an issue with flushing/buffering.

Do you still have the issue when using spawnSync instead of spawn or exec? You may also be able to work around the issue by piping the output into a file, then reading from that file with fs
