Vector search returns 500 server error on large datasets

[bajahranks]

I created a database with 2 tables. One table that holds the data that will be transformed into chunks and another table that has the vector embeddings of each of the chunks created. I created an edge function to execute the similarity search. The search runs successfully when I use a small subset of the records, like 20 records. However, the table has approximately 35000 records. When I run the query on all 35k records, the response is null with a 500 Internal Server Error. The table size with the vector embeddings is approximately 350MB.

Is this happening because I'm on the free plan? Would upgrading to the PRO version solve this issue? Do I need any addons to the PRO plan?
