If I'm receiving JSON from an external API and encounter "expected 'number' but got 'string'", how should I troubleshoot the issue?

1. Examine the API's documentation to understand the expected data types. 2. Use a tool like `curl` or Postman to fetch the raw JSON and inspect the problematic field. 3. If the API returns incorrect data, consider reporting the bug to the API provider. 4. If you have control over the parsing, you might need to preprocess the data, such as converting string representations of numbers to actual numbers before using them in calculations.
