couldn't find output binding serving-fv9tm-bindings-httpz-m5cbd #132

Closed uestczz closed 1 year ago

uestczz commented 1 year ago

I'm trying the sample named with-output-binding, and function-front.yaml may confuse me. so I make my yaml based on the readme. k8s v1.26.0 openfunction/openfunction:v1.1.1 my serving config is as below: ‘‘‘ apiVersion: core.openfunction.io/v1beta2 serving: scaleOptions: minReplicas: 0 maxReplicas: 5 outputs:

and my code is as below: req := CorpIDToOpenReq{ CorpID: "xxxxxxx", } data, _ := json.Marshal(req) bytes, err := ctx.Send("httpz", data) if err != nil { return ctx.ReturnOnInternalError(), err } Then a error raised: 2023/09/07 02:04:14 httpz 2023/09/07 02:04:14 {httpz serving-fv9tm-bindings-httpz-m5cbd bindings.http map[] post} 2023/09/07 02:04:14 httpy 2023/09/07 02:04:14 {httpy serving-fv9tm-bindings-httpy-v2t64 bindings.http map[] get} 2023/09/07 02:04:14 [123 10 9 34 110 34 58 32 49 10 125] 2023/09/07 02:04:15 error invoking binding serving-fv9tm-bindings-httpz-m5cbd/post: rpc error: code = Internal desc = error when invoke output binding serving-fv9tm-bindings-httpz-m5cbd: couldn't find output binding serving-fv9tm-bindings-httpz-m5cbd

I print the output map, there's a key named httpz. and I want to invode a nodapr httpendpoint. so what's wrong with my code.

Run the following command and paste the result.

kubectl get servings serving-fv9tm -n < namespace > -oyaml
kubectl get components -A

@wanjunlei i update my function, so the name may changes. 2023/09/07 06:04:56 httpz 2023/09/07 06:04:56 {httpz serving-2xtn4-bindings-httpz-47wjs bindings.http map[] post} 2023/09/07 06:04:56 httpy 2023/09/07 06:04:56 {httpy serving-2xtn4-bindings-httpy-694tj bindings.http map[] get} 2023/09/07 06:04:56 [123 10 9 34 110 34 58 32 49 10 125] 2023/09/07 06:04:57 error invoking binding serving-2xtn4-bindings-httpz-47wjs/post: rpc error: code = Internal desc = error when invoke output binding serving-2xtn4-bindings-httpz-47wjs: couldn't find output binding serving-2xtn4-bindings-httpz-47wjs

@wanjunlei do you have wechat group, or online meeting? I read the code of function "parseContext" in the repo functions-framework-go. but it just unmarshal the env data. so how are the outputs in yaml transformed to data in env.

wanjunlei commented 1 year ago

you can join our discord channel

uestczz commented 1 year ago

@wanjunlei so could you please help me solve my problem? and I paste the result of your cmd.

wanjunlei commented 1 year ago

You need to add httpz to the spec.bindings like the spec.bindings.httpy

uestczz commented 1 year ago

@wanjunlei there's also the same problem with httpy. 2023/09/07 07:55:57 error invoking binding serving-2xtn4-bindings-httpy-694tj/get: rpc error: code = Internal desc = error when invoke output binding serving-2xtn4-bindings-httpy-694tj: couldn't find output binding serving-2xtn4-bindings-httpy-694tj

the specs of httpz and httpy are the same.

wanjunlei commented 1 year ago

I think this error is related to the dapr component, OpenFunction has created the dapr component but the component doesn't seem to be ready yet, please check first.

uestczz commented 1 year ago

@wanjunlei how to check it. openfunction is composed of dapr. I decide to use openfunction in production environment. any company has used it?

dapr components -k

wanjunlei commented 1 year ago

you can try this 

dapr invoke --app-id serving-2xtn4-bindings-httpy-694tj --verb GET
uestczz commented 1 year ago

dapr invoke is only used for self-hosted, and invoke. my sample is binding.

dapr -h

so there's a component definition named serving-wb7q9-bindings-httpz-pdk85.

but I use curl, the same error occur.

curl -H "Content-Type: application/json" -H "dapr-app-id: go-bind-http-default" -X POST -d "{ \"operation\": \"post\" }" 'http://10.98.248.56:3500/v1.0/bindings/serving-wb7q9-bindings-httpz-pdk85'
{"errorCode":"ERR_INVOKE_OUTPUT_BINDING","message":"error when invoke output binding serving-wb7q9-bindings-httpz-pdk85: couldn't find output binding serving-wb7q9-bindings-httpz-pdk85"}

10.98.248.56 is the endpoint of svc go-bind-http-default. it points to a proxy. so dapr doesn't load the definition of my component. And can you give some suggestions? @wanjunlei

wanjunlei commented 1 year ago

Please check the dapr controller logs first, maybe there is some helpful information.

uestczz commented 1 year ago

@wanjunlei I found some errors from dapr-operator. there's something wrong with anothor component. so maybe daprd for this func failed when creating.

I think this log has nothing to do with the error above, maybe you can enable the debug log to get more information.

uestczz commented 1 year ago

@wanjunlei I delete the state store dapr component. dapr becomes okay. but now my function has no address. I don't know why.

The function serving is starting, maybe there is some error about knative.

Run this command to check the status

kubectl get ksvc
