panic: runtime error: invalid memory address or nil pointer dereference in v1.5.1 and v1.5.2

[j4zzcat]

Hello, I have a terraform script that works well with v1.5.0.
However, with version 1.5.1 and 1.5.2 terraform crashes with panic, indicating a 'panic: runtime error: invalid memory address or nil pointer dereference'.

[hkantare]

Can you let us know did you set the ibmcloud api key either in provider block or via environmental variable(IC_API_KEY)

[j4zzcat]

Env variable 'IBMCLOUD_API_KEY'.

[hkantare]

Can you confirm the value for IBMCLOUD_API_KEY is not empty we are able to reproduce this issue only when the API key is empty...

[j4zzcat]

Confirmed.
