解决AdWords脚本‘Parsing Error: Please check your selector. (line XX)’错误

Hey there! I totally get how frustrating it is to hit this kind of error when you’re not a full-time developer—AdWords scripts can feel like a black box sometimes, especially when you’re just starting out. Let’s walk through this together to figure out what’s going wrong.

That "Parsing Error: Please check your selector" message almost always points to an issue with how you’re telling the script to pull data from your Google Ads account. Selectors are the bits of code that look like AdsApp.campaigns().withCondition(...) or AdsApp.keywords().withIds([12345])—they’re how you filter and fetch specific items from your account.

Here are some simple, actionable checks you can do on line XX (the one the error mentions):

• Double-check your condition syntax: Google Ads uses its own query language for these selectors, not regular JavaScript. For example, use = instead of == for comparisons, and make sure any text values are wrapped in single quotes. So Status = 'ENABLED' is correct, but Status == "ENABLED" will break things.
• Verify field names are correct: The field you’re filtering on (like Name, Status, BudgetAmount) has to match the exact names Google uses. You don’t have to memorize them—just think about what you’re trying to filter, and if you’re unsure, cross-reference with the Google Ads Scripts reference for the object you’re working with (like campaigns or ad groups) to confirm the right field names.
• Check for unclosed quotes: This is super common! If your condition has a string (like filtering by campaign name), make sure you have a matching opening and closing quote. For example, "Name CONTAINS 'Summer Sale'" is good, but "Name CONTAINS 'Summer Sale (missing the closing single quote) will throw this error.
• Make sure you’re using the right selector method: If you’re trying to get ad groups, use AdsApp.adGroups() (plural) instead of a misspelled version like AdsApp.adGroup()—tiny typos like this can trigger parse errors too.

Let me give you a quick example of a broken selector vs a fixed one:

Broken code (your line XX might look like this):

// Wrong: Uses JS's ==, misspelled field name, mismatched quotes
AdsApp.campaigns().withCondition("status == "Summer Campaign"")

Fixed code:

// Correct: Uses =, proper field name, single quotes inside double quotes
AdsApp.campaigns().withCondition("Status = 'Summer Campaign'")

If you can share the exact code from line XX (and maybe the lines around it), I can help you spot the exact issue right away. No need to worry about being "not a developer"—these are all tiny, easy-to-fix mistakes that trip up even experienced folks sometimes!
