Error: Failed to snapshot the working copy
The file '$TEST_ENV/repo/large' is too large to be snapshotted: it is 3 bytes too large; the maximum size allowed is 10 bytes (10.0B).
Hint: This is to prevent large files from being added on accident. You can fix this error by:
- Adding the file to `.gitignore`
- Run `jj config set --repo snapshot.max-new-file-size 13`
This will increase the maximum file size allowed for new files, in this repository only.
- Run `jj --config-toml 'snapshot.max-new-file-size=13' st`
This will increase the maximum file size allowed for new files, for this command only.
