You didn't paste the code, but 90% of "why isn't this working" posts boil down to one of these:

• You have a typo in an import or variable name (IDE linter will show it)
• The API endpoint requires an auth header you forgot
• You're passing ['a'] instead of 'a' (or vice versa)
• Async function being called without await — the code runs but returns a Promise object, not your value

Paste the snippet and I can actually help.
