Supabase Edge Functions are serverless functions that run close to your users, providing low-latency responses. They are built on top of Deno and allow developers to execute backend logic without managing infrastructure. These functions are ideal for handling tasks such as authentication, data processing, and integrating with third-party services.
When using Supabase Edge Functions, you may encounter an issue where the function output is unexpectedly truncated. This can lead to incomplete data being returned to the client, causing potential disruptions in application functionality.
Developers might notice that the data returned from a function call is incomplete. This could manifest as missing fields in JSON responses or incomplete text data, leading to errors in the client application.
The EF035 error code indicates that the output of a Supabase Edge Function is too large, resulting in truncation. This typically happens when the function attempts to return a payload that exceeds the size limits imposed by the platform.
Supabase Edge Functions have a maximum response size limit to ensure optimal performance and resource usage. When this limit is exceeded, the output is truncated, and the EF035 error is triggered.
To address the EF035 error, you can take several steps to reduce the size of the function output or manage it more effectively.
Examine the data being returned by your function and identify any unnecessary fields or data that can be omitted. Consider returning only the essential data needed by the client.
If your function returns a large dataset, consider implementing pagination. This involves breaking down the data into smaller chunks and returning them in separate requests. You can use query parameters to specify the page number and size. For more information on implementing pagination, refer to the Supabase Pagination Guide.
Consider compressing the response data before sending it to the client. This can significantly reduce the size of the data being transmitted. You can use libraries such as Deno Compress to achieve this.
By understanding the limitations of Supabase Edge Functions and implementing strategies to manage output size, you can effectively resolve the EF035 error. This ensures that your applications continue to function smoothly without data truncation issues.
