Prismic filters – error 500 when field not available in prismic

If you’re working with Prismic and encountering an error 500 when a field is not available in Prismic, don’t worry, you’re not alone. This issue can be quite frustrating, but there are a few solutions you can try to resolve it.

Solution 1: Check if the field exists

The first solution is to check if the field exists in Prismic before accessing its value. You can use the has method provided by the Prismic API to check if the field exists. Here’s an example:

// Check if the field exists
if (document.has('field_name')) {
  // Access the field value
  const fieldValue = document.get('field_name').value;
} else {
  // Handle the case when the field is not available
  console.error('Field not available in Prismic');
}

Solution 2: Use a default value

If the field is not available in Prismic, you can also use a default value to prevent the error. This can be useful when you want to display a fallback value or handle the missing field gracefully. Here’s an example:

// Access the field value with a default value
const fieldValue = document.get('field_name')?.value || 'Default Value';

In this example, if the field is not available, the document.get('field_name') expression will return undefined. The optional chaining operator ?. will handle this case and prevent an error. If the value is undefined, the default value 'Default Value' will be used instead.

Solution 3: Use conditional rendering

Another solution is to use conditional rendering to only display the field if it exists in Prismic. This can be done using an if statement or a conditional rendering library like React’s jsx. Here’s an example using React:

{document.has('field_name') && (
  

    Field Value: {document.get('field_name').value}
  
)}

In this example, the && operator is used to conditionally render the
