Custom Provider issue

After updating to 0.12 terraform plan fails with this message

I have a custom terraform provider to integrate with our authentication service. Worked great with 0.11 …

Error: Failed to retrieve schema from provider “ibmispim”: rpc error: code = Unavailable desc = all SubConns are in TransientFailure, latest connection error: connection error: desc = “transport: authentication handshake failed: tls: first record does not look like a TLS handshake”

Any suggestions ?

Can you share any more information about your provider? Is it importing or What version of whichever it’s importing is it using?

It’s importing the in the code.

I’d recommend updating to use There’s more information on that on our website.

Regardless of that, however, is there a version pinned in your go.mod? What version or SHA of are you importing?
