Steps to reproduce the problem

Run docker compose Run Jupyter notebook Run docs/guides/03_runtime_primitives_with_quantum_serverless.ipynb

What is the current behavior?

It fails with the following error.

What is the expected behavior?

Run without error.

[akihikokuroda]

I wonder if this should run. Do we need embed an account?

[IceKhan13]

I will cover this under #479

Now we can pass runtime service object as argument. We will use that to handle account details
