http_client cannot increase buffer

[gajus]

Getting this error:

[2022/12/08 00:18:26] [ warn] [http_client] cannot increase buffer: current=32000 requested=64768 max=32000
[2022/12/08 00:18:26] [ warn] [http_client] cannot increase buffer: current=32000 requested=64768 max=32000
[2022/12/08 00:18:45] [ warn] [http_client] cannot increase buffer: current=32000 requested=64768 max=32000

As far as I understand, this error is complaining about input being larger than 32K. I tried increasing the settings that I've found, but the error persists. This is our current setup:

[INPUT]
    Name tail
    Path /var/log/containers/*.log
    multiline.parser docker, cri
    Tag kube.*
    Mem_Buf_Limit 5MB
    Skip_Long_Lines On
    Buffer_Chunk_Size 64KB
    Buffer_Max_Size 128KB

Turns out this error was coming from FILTER. Adding Buffer_Size fixed it.

filters: |
  [FILTER]
      Name kubernetes
      Match kube.*
      Merge_Log On
      Keep_Log Off
      K8S-Logging.Parser On
      K8S-Logging.Exclude On
+      Buffer_Size 64KB
