OSError: could not extract source code

[exa-eswar]

if we run the following example in Jupyter notebook or Ipython in general, I am getting OSError: could not extract source code

from exasol_udf_mock_python.udf_mock_executor import UDFMockExecutor
from exasol_udf_mock_python.mock_meta_data import MockMetaData
from exasol_udf_mock_python.column import Column

def udf_wrapper():

    def run(ctx):
        return ctx.t1+1, ctx.t2+1.1, ctx.t3+"1"

executor = UDFMockExecutor()
meta = MockMetaData(
    script_code_wrapper_function=udf_wrapper,
    input_type="SCALAR",
    input_columns=[Column("t1", int, "INTEGER"),
                   Column("t2", float, "FLOAT"),
                   Column("t3", str, "VARCHAR(20000)")],
    output_type="RETURNS",
    output_columns=[Column("t1", int, "INTEGER"),
                    Column("t2", float, "FLOAT"),
                    Column("t3", str, "VARCHAR(20000)")]
)
exa = MockExaEnvironment(meta)
result = executor.run([Group([(1,1.0,"1"), (5,5.0,"5"), (6,6.0,"6")])], exa)

result

I can't reproduce it with Python 3.8.10 and Jupyter Notebook 7.0.4

I assume the following imports were just missed in the problem description.

from exasol_udf_mock_python.mock_exa_environment import MockExaEnvironment
from exasol_udf_mock_python.group import Group
