images.urls.command is empty

Error message

images.urls.command is empty

What it means

createCommandUploader builds a BlobUploader from an argv template string (images.urls.command in config). After splitting the template, if no arguments remain the command is useless, so it throws immediately. This is a synchronous, configuration-time validation error.

Solutions

1. Set images.urls.command to a real command template, e.g. "curl -F 'file=@{file}' https://0x0.st"
2. Remove the empty images.urls.command key if you do not want the command destination
3. Check the config file section actually saved (empty string vs commented-out line)
4. Validate the template contains {file} as well, since a non-empty template without {file} throws the next error

Example fix

// before
"urls": { "command": "" }
// after
"urls": { "command": "curl -sF 'file=@{file}' https://0x0.st" }

const cmd = config.images?.urls?.command;
if (typeof cmd !== "string" || cmd.trim().length === 0) {
	throw new Error("images.urls.command must be a non-empty command template");
}

function hasCommandTemplate(c: unknown): c is { command: string } {
	return typeof c === "object" && c !== null && typeof (c as { command?: unknown }).command === "string"
		&& (c as { command: string }).command.trim().length > 0;
}

try {
	const uploader = createConfiguredUploader("command", config);
} catch (err) {
	if (err instanceof Error && err.message === "images.urls.command is empty") {
		// prompt user to fill images.urls.command in config
	}
	throw err;
}

When it happens

Trigger: Configuring images.urls.command as an empty string or whitespace-only string; the template consists solely of characters that splitCommandTemplate strips (quotes/spaces), yielding zero argv entries.

Common situations: Config placeholder left unfilled ("command": "") after copying a config template; YAML/TOML key present but value empty; quoting mistakes that collapse the value to nothing.
