A file name a server cannot hold

  ✗ dist/notes\draft.txt cannot be sent as it is named.
    Its name holds a \, which a server could read as a folder separator.
    Rename it, or leave it out with exclude in sealup.yml.

Exit code: 6. Server changed: no.

What happened

A file to upload has a name that cannot be a path on the server: a control character (a line break, a tab), a \, or a start like a Windows drive (C:).

Why

On the server such a name could land in another folder than the one you meant, or not at all. sealup checks every name before it connects.

The fix

Rename the file, or leave it out with exclude: in sealup.yml.
