Hi, When trying to update embeddings from haystack, I am getting the following error ```auto Reason: Gateway Timeout HTTP response headers: HTTPHeaderDict({'content-type': 'text/plain', 'content-length': '24', 'date': 'Wed, 07 Jun 2023 23:47:51 GMT', 'server': 'envoy'}) HTTP response body: upstream request timeout ``` I have been running the same code snippet for the couple of weeks but it has stopped working for me today. I was wandering if I hit a free tier limit somewhere. I would be grateful if anyone can help me solve the problem ---

Hi @ashutosh. Please check your email, I just sent you a proactive ticket on this issue. The short version is your index has a very high degree of cardinality which is preventing it from being built. ---

Also getting this error, was working fine yesterday. I have a much smaller index (1/100th) the size that works ok, but my main large index has been off and on all day with this same error. ---

It decided to work fine again now. That’s good, but unreliable. We still have no clue why it went down last night and when that would happen again. ---

Hello all, 504 error is a genric error and there can be a number of different causes, some trigger by user actions and other times there is an internal error on our side. Unfortunely there is not a sliver bullet soultion and each case has to be looked at in turn. In most case the problem is when the index is overloaded for exampling: - Trying to put 3 million vectors with 512 dimensions into a `P1.x1` configuration when it can support about [1,250,000](https://docs.pinecone.io/guides/indexes/choosing-a-pod-type-and-size) - Large [Metadata cardinality and size](https://docs.pinecone.io/guides/indexes/choosing-a-pod-type-and-size#metadata-cardinality-and-size) when there is no [Selective metadata indexing](https://docs.pinecone.io/guides/indexes/configure-pod-based-indexes#selective-metadata-indexing) In both of these cases increasing the size of the pod resolves the issue. The good news is that our new serverless index address these points and many others. ---

Thanks! We’re trying out the new serverless index this week
