[BUG] Cannot convert undefined or null to object - Redis Vector Store

[danielstankw]

Due to the issues I had with In-memory vector store I have switched it to the Redis one. Every time I attempt to Upsert Vector Database I get the following error":

do you have Redis Stack running on Docker? https://redis.io/docs/latest/operate/oss_and_stack/install/install-stack/docker/

1.) My Flow:

2.) Upsert result

3.) Vectors on Redis that were upserted:

Do you have any suggestions for some steps worth taking to troubleshoot it? - for me the results arent upserted.

[HenryHengZJ]

in your flow, you are using LocalAI and Azure, I'd suggest try replacing each one at at time to see which one was causing issue. Also, is it just PDF? have you tried Text file?

[danielstankw]

@HenryHengZJ Do I need to have redis stack running in docker to use this application? I am connecting to redis that is hosted externally.

Yes, can confirm this is happening for me also using the pdf loader. It seems that this is the case with some of the pdf file, not all. Found this similar issue https://github.com/FlowiseAI/Flowise/issues/2099
