Hello Knime Community, I have seen several posts with a simliar question, but was not able to get a solution. We are using an external service called Mindee, where documents are processed and extracted data from the document is sent back. Was someone in the meantime able to get a working solution? A other way I tried was with the new Python Nodes. But the error message I received was: Execute failed: TypeError: expected str, bytes or os.PathLike object, not ArrowSourceTable Source Example: from mindee import Client, PredictResponse, product # Init a new client mindee_client = Client(api_key="my-api-key-here") custom_endpoint = mindee_client.create_endpoint("my_endpoint", "my_user") # Load a file from disk input_doc = mindee_client.source_from_path("/path/to/the/file.ext") #Load a file from disk and parse it. # The endpoint name must be specified since it cannot be determined from the class. result: PredictResponse = mindee_client.parse(product.CustomV1, input_doc, endpoint=custom_endpoint) # Print a brief summary of the parsed data print(result.document) > When I use the os Modul in the node to get the files.The following Error ocurred: KnimeUserError: Output table ‘0’ must be of type knime.api.Table or knime.api.BatchOutputTable, but got <class ‘mindee.parsing.common.document.Document’> So I need to get the result.document into a Knime-Table. Thanks and have a nice day, Sven

@sven-abx I assume you would need just a string with a path and not a tupel. Maybe you ask ChatGPT what the right syntax for your case is. You might have to loop thru your dataframe using index and row and then within the loop the syntax would be like row["path"] like in this example [image] Python scripts in Loops KNIME Extensions @ActionAndi a solution could look something like this: [image] kn_example_python_loop_graphic_restart.knwf (164.6 KB) The script would look like this: import knime.scripting.io as knio # This example script creates an output table containing randomly drawn integers using numpy and pandas. import numpy as np import pandas as pd import matplotlib.pyplot as plt var_data_path = knio.flow_variables['context.workflow.data-path'] # Load your data into a Pandas DataFrame # df = pd.read_csv(v… [image] Python - loop thru data rows and create PNG files within a loop - store which... Python - loop thru data rows and create PNG files within a loop - store which items have already been processed

@sven-abx the code is not good to read, maybe try another format

Then: you will have to convert the data into a pandas dataframe and subsequently into an arrow table to get the content back to knime:
