at EventEmitter.set (/path/to/folder/ioredis/built/utils/Commander.js:95:63)I tried these two workarounds which worked fine, but they are not wanted
- Use a separate
.pipeline()for all of our writes and left all reads on the auto pipeline -> everything worked well and without these two errors. - Set
scaleReadstomaster-> everything worked well and without these two errors.
I am using:
- ioredis: 5.2.4
- node: v16.15.1
- npm: 9.2.0
- redis in cluster mode
- 3 masters
- 3 slaves (replicas)
