I’m trying to specify an array of hashes when deploying a helm chart. The yaml looks like this: myvals: - name: thefirsthost token: apitoken1 - name: thesecondhost token: apitoken2 If I only specify a few of them, I only get the below error for about a minute, and then it goes away and everything works fine. If I drop in 20+, the error never goes away. It seems like the number of errors thrown grows exponentially as I add elements. I’m trying to specify this as key=values in rancher like so: - myvals[0].name=thefirsthost - myvals[0].token=apitoken1 - myvals[1].name=thesecondhost - myvals[1].token=apitoken2 It feels like the error below is telling me that myvals[0] is null and therefore I can’t access the .name and .token attributes. That makes sense, but I can’t think of another way to specify the overrides in rancher. Helm template failed. panic: interface conversion: interface {} is nil, not map[string]interface {} goroutine 1 [running]: [k8s.io/helm/pkg/strvals.(\*parser](http://k8s.io/helm/pkg/strvals.(*parser)).listItem(0xc4209537a0, 0xc42091dea0, 0x7, 0x7, 0x3, 0x1, 0x5b, 0x0, 0x0, 0x0) (there is a slew of other go mess at the end, but the rancher forum isn’t letting me paste it in. ---

I’ve got same error in Rancher v2.1.8 / Rancher-CLI v2.2.0. Is there any workarounds? ---

The only “workaround” is to hardcode your values into the questions.yaml or values.yaml. I’ve mostly done questions yaml - took the approach of having only a a couple of questions for the person to answer - like “environment” = PRD, QA, DEV. And from that answer, i just assume the values they want. Would love a better workaround. ---

Rancher team is working on a fix for this. See [https://github.com/rancher/rancher/issues/20310](https://github.com/rancher/rancher/issues/20310)
