Fabric SDK unable to initialize cryptosuite config - go

Question

I'm running a business network on IBM Cloud Blockchain Platform 2.0. I downloaded a connection profile from the instantiated smart contracts section on the Platform Console, and am trying to connect using the Fabric SDK for Go but I am facing an error.
This is my current relevant code, under main
configOpts := fabricConfig.FromFile("./profiles/flex.json")
fabSDK, err := fabsdk.New(configOpts)
if err != nil {
entry.WithError(err).Fatal("Error setting up Fabric SDK")
}
defer fabSDK.Close()
Expected: Connects to the business network instance
Actual: I get an error
FATA[0000] Error setting up Fabric SDK env=DEV
error="failed to initialize configuration: unable to initialize cryptosuite using crypto suite config:
failed to initialize crypto suite: Unsupported BCCSP Provider: "

Answer 1

I add "cryptoconfig" path to the client.
BCCSP is optional, and you can remove.
I added the sample config, please see below.
