Broken notebook test:

• Cell In[19], line 12 (Cell Index starts a 2 apparently)
• ETL-2210: AWS URL is invalid: Provided URL is not a valid AWS S3 URL(AI_LAB_FIRST_STEPS_S3/first_steps/US_FLIGHTS_FEB_2024.parquet).
• Build logs

source code

from exasol.nb_connector.connections import open_pyexasol_connection

query = "IMPORT INTO {table!q} FROM PARQUET AT {connection} FILE {file!s}"

params = {
    "table": (ai_lab_config.db_schema, "US_FLIGHTS"),
    "connection": "AI_LAB_FIRST_STEPS_S3",
    "file": "first_steps/US_FLIGHTS_FEB_2024.parquet",
}

with open_pyexasol_connection(ai_lab_config, compression=True) as conn:
    result = conn.execute(query, params)
print(f"Imported {result.rowcount()} rows.")

Assumed mistake: prepared statement needs to mention connection with formatting !q or !r.
