Failed to update setting: invalid composer vim mode '{value}

Error message

Failed to update setting: invalid composer vim mode '{value}'. Expected: normal, vim.

What it means

Settings update validation for the composer vim-mode key: the normalized value is neither vim nor normal. The guard runs before the flag is stored so the composer cannot end up in an undefined input mode.
