buffer has no file

Error message

buffer has no file

What it means

get_permalink_to_line requires a file-backed buffer, but File::from_dyn on the buffer's file returned None (untitled buffer or non-local file), so there is no repository path from which to build a permalink.

Solutions

1. Save the buffer to a file inside a git worktree and retry
2. Disable permalink/copy-permalink UI actions for buffers without a local file
