I created a ADF pipeline to ingest data from multiple csv files into the tables that I manually created in Postgressql database. However while running the pipeline threw me an error : "
'Type=Npgsql.PostgresException,Message=42P01: relation "public.order_products__train.csv" does not exist,Source=Npgsql,"

I have already created the tables though. Does anyone have a solution to fix this?

    Hi @Yi hui Teh ,

    Welcome to Microsoft Q&A forum and thanks for posting your query here.

    From the error message my understanding is that it could be a configuration issue.

    Here the 42P01 denotes an undefined table. PostgreSQL error 42P01 denotes the database query is on an undefined table. This error usually occurs due to improper database setup, unidentified table name.

    From the error message 'Type=Npgsql.PostgresException,Message=42P01: relation "public.order_products__train.csv" does not exist,Source=Npgsql," it seems like your sink data set configuration or the query might be pointing to a wrong table name. Have you configured public.r_ordeproducts__train.csv as table name in your configuration? But looking at the screenshot your table name is order_products_train and the error message clearly states that you are passing public.r_ordeproducts__train.csv as your sink table name which is a mismatch with actual table name order_products_train in the database and hence you are receiving this issue.

    I would recommend you to please double check your configuration to make sure table names are configured correctly in your pipeline flow to avoid this issue.
