[BUG] Expected property name or '}' in JSON at position 1

[yyoussef11]

Describe the bug When running a chatflow using ollamaembeddings and Redis VectorStore i am receiving this error :

SyntaxError: Expected property name or '}' in JSON at position 1 at JSON.parse () at similaritySearchVectorWithScore (~\Flowise\packages\components\dist\nodes\vectorstores\Redis\Redis.js:276:44) at process.processTicksAndRejections (node:internal/process/task_queues:95:5) at async vectorStore.similaritySearchVectorWithScore (~\Flowise\packages\components\dist\nodes\vectorstores\Redis\Redis.js:214:20) at async RedisVectorStore.similaritySearch (~\Flowise\node_modules.pnpm\@langchain+core@0.2.14langchain@0.2.3@aws-sdk+client-s3@3.529.1_@aws-sdk+credential-provide_iy4pkl2ze2vpuxlmnivkyhhz5q\node_modules\@langchain\core\dist\vectorstores.cjs:108:25)

To Reproduce Build a chatflow with "Recursive Character Text Splitter", Read from a folder, pass the document to a Redis vector store Use OllamaEmbeddings and use ChatOllama and Convesational Retrieval QA Chain

Expected behavior The pexected behavior is after upserting the files, when communicating with the Chatflow i want to receive results.

does it works with other embeddings? or does ollama embedding work with other vector store

[yyoussef11]

@HenryHengZJ actually when i changed the "top k" value of the Redis retriever from 1000 to 100, it didn't fail. Noting that the same "top k" value is used with another embedded data, and it worked.

Could it be the amount of embedded data was not enough?

to answer your questions: Ollama Embeddings worked with In Memory vector store

[HenryHengZJ]

I am guessing there might be some sort of rate limit from Redis? or from the embeddings side
