No script name provided.

Error message

No script name provided.

What it means

Thrown by onRegexImportObjectChange during regex object import when the incoming regexScript has no scriptName. A script name is required to register the script (it is the user-facing identifier and used for toggling/listing), so an import payload missing it is rejected before a UUID is assigned and the script pushed.

Solutions

1. Ensure the import object has a non-empty scriptName: regexScript.scriptName = regexScript.scriptName || 'Imported Script'.
2. Validate the payload schema before import: assert typeof obj.scriptName === 'string' && obj.scriptName.trim().
3. If importing from a UI, require the name field and disable import until filled.

Example fix

// before
{ "findRegex": "/foo/g", "replaceString": "bar" }

// after
{ "scriptName": "Foo to Bar", "findRegex": "/foo/g", "replaceString": "bar" }

if (typeof regexScript.scriptName !== 'string' || regexScript.scriptName.trim().length === 0) {
    throw new Error('Cannot import: regexScript.scriptName is missing or empty');
}
await onRegexImportObjectChange(regexScript, scriptType);

/** @param {unknown} x */
const hasScriptName = (x) => typeof x?.scriptName === 'string' && x.scriptName.trim().length > 0;

try { await onRegexImportObjectChange(regexScript, scriptType); }
catch (e) { if (/No script name/.test(e.message)) { console.warn('skipping unnamed regex import'); } else throw e; }

When it happens

Trigger: Importing a JSON regex object whose scriptName field is empty/missing; a malformed export file; programmatic import of a partial object.

Common situations: Hand-edited regex JSON lacking the name; third-party regex packs with inconsistent schema; converting a find/replace snippet into an import object and forgetting the name.
