Exporting project gives connection not found error

[Musketeers]

Hi, In Dataiku, I am trying to export a project from project home page --> action --> Export project.

It seems that one of the connection to a dataset is deleted because of non use or some other reason.

Is it possible to export this project without that dataset connection.

Hi,

In this case, you should identify the stale connection and update the respective dataset/s to a working connection or a dummy connection that exists as you can later remap these when importing the project. 

The error should indicate the connection name to list all datasets using that connection you can run the following in a Notebook :

import dataiku
client = dataiku.api_client()

# Get project using the ProjectKey
proj = client.get_project('project-name')

# List all datasets within the project
my_list = proj.list_datasets()
# set name of the connection that is missing
bad_connection = "name-of-deleted-connection"

# For each filesystem managed dataset, change connection to new filesystem connection
for my_data in my_list:
    dataset = proj.get_dataset(my_data["name"])
    my_def = dataset.get_definition()
    if my_def["params"]["connection"] == bad_connection:
        print(dataset.dataset_name)

Then you can edit the connection to a valid connection for the dataset names that are printed.

Hi
I have the same issue, but in a python script (using the API)

Can I force the export ?

Or should I find the dataset and replace its connections, but then can I replace it with "None" or empty ?

Hi @JulienD 

You can create dummy connection that doesn't necessarily work of the same type but you should update the missing connection before exporting with code or manually.
