ResponseError: Invalid field type for field `content_vector`

[hack-r]

This is for the Chatbot app.

I have the Redisearch module loaded. The errant code:

# Optional step to drop the index if it already exists
#redis_client.ft(INDEX_NAME).dropindex()

# Check if index exists
try:
    redis_client.ft(INDEX_NAME).info()
    print("Index already exists")
except Exception as e:
    print(e)
    # Create RediSearch Index
    print('Not there yet. Creating')
    redis_client.ft(INDEX_NAME).create_index(
        fields = fields,
        definition = IndexDefinition(prefix=[PREFIX], index_type=IndexType.HASH)
    )

Output:

Unknown Index name
Not there yet. Creating

I'm facing the same issue, any hints on how to resolve this ?

[mangopeaches]

I believe this is an issue with your version of redisearch. I was just using 2.0.2 and getting this error, but it worked once I switched to 2.4.3.

I was just running redis locally with the docker images.

Works:
docker run -p 6379:6379 redislabs/redisearch:2.4.3

Error you're experiencing:
docker run -p 6379:6379 redislabs/redisearch:2.0.2

This solution works!!
Thanks!!

Can confirm -- please make sure to use the latest version of RediSearch module within Redis Stack: https://redis.io/docs/stack/get-started/install/docker/ OR signup for a hosted instance on Redis Cloud to not deal with the hassle of managing it.

The officially recommended docker command (from link above):

docker run -d --name redis-stack -p 6379:6379 -p 8001:8001 redis/redis-stack:latest
