I use n8n with the kubernetes helm chart.
You only need to set the following annotation:
ingress.kubernetes.io/compress-enable: “false”
Would be nice if this would be included by default in the helm chart…
It is described here: k8s-ts-ingress/compression.md at master · torchbox/k8s-ts-ingress · GitHub
Anyway, thank you for the hint with compress
