SDK_CREDENTIAL_CONFIGURATION_INVALID
Cause
createSplitchClient was given no credential, or both a clientKey and an apiKey.
Fix
Pass exactly one. Use clientKey (the pk_… key material from splitch client-key get) for anything that evaluates, including servers. Use apiKey (sk_…, servers only) for peekVariant. The two unlock different methods, so the client cannot pick for you.
