[BUG] Error 400 when HTTP PUT to Qdrant: Format error in JSON body: data did not match any variant of untagged enum VectorStruct #9266
Description
Problem (one or two sentences)
Hi!
Tried with several embeddings in version 3.32.0.
Some requests work and at some point it fails and never finishes indexing: blue progress bar gets stuck
In Roo: Error - Failed during initial scan: Indexing failed: Failed to process batch after 3 attempts: Bad Request
