Concurrency error when using wskdebug with IBM Cloud Functions #30
Description
Version
wskdebug --version
1.0.10
Description
I am trying to use wskdebug with IBM Cloud Functions.
Step 1: My action is very simple
function main(args) {
if (args && args.name) {
console.log(`hello ${args.name}`);
return { msg: `hello ${args.name}` };
} else {
console.log(`hello world`);
return { msg: `hello world` };
}
}
Step 2: Created the action on IBM Cloud
ibmcloud fn action create hello-debug index.js
Step 3: started wskdebug
I get an error when it tried to create the temporary Agent action. I don’t need the LiveReload support.
Error
$ wskdebug hello-debug index.js -v

Restoring action
Workaround by @alexkli
It should normally automatically pick a different agent that does not require the concurrency feature, but I guess that detection is not perfect yet (it looks at the swagger api docs and maybe the ibm cloud has different information in there).
As alternative, you can try the ngrok option using --ngrok. It should just work - you don’t even need an ngrok.com account.
