Panic with 1.25.8

hi @ctindel !!

I have just faced this exact same error recently.

Are you by any chance updating an object and not passing a TEXT_ARRAY?

here is a code I was able to run and reproduce and get this error message:

import weaviate
from weaviate.util import generate_uuid5
from weaviate import classes as wvc
client = weaviate.connect_to_local()

print(weaviate.__version__, client.get_meta().get("version"))

client.collections.delete("Test")
collection = client.collections.create(
    "Test",
    properties=[
        wvc.config.Property(
            name="tags", data_type=wvc.config.DataType.TEXT_ARRAY),
        wvc.config.Property(
            name="title", data_type=wvc.config.DataType.TEXT),
        wvc.config.Property(name="authorized",
                            data_type=wvc.config.DataType.BOOL)
    ],
    vectorizer_config=[
        wvc.config.Configure.NamedVectors.text2vec_openai(
            name="title_vector",
            source_properties=["title"],
        ),
        wvc.config.Configure.NamedVectors.text2vec_openai(
            name="tags_vector",
            source_properties=["tags"],
        ),
    ]
)

collection.data.insert({"tags": [], "authorized": False, },
                       uuid=generate_uuid5("example2"))
# this will fail:
collection.data.update(
    properties={
        "authorized": True,
        #"tags": [] # specifying it null will work
    }, uuid=generate_uuid5("example2"))
#
