How to fix the error
Set up Manual Advanced Matching
1. Open your website's code2. Search fbq('init'...) to find places where you are using the Meta Pixel3. Update the code block to include advanced matching data as the third parameter.
For example, your pixelID is 2238494856681190, you should add this to your website's code:
fbq('init', '2238494856681190', {
em: 'email@email.com', // Values will be hashed automatically by the pixel using SHA-256
ph: '1234567890',
...
});
