Can not download datasources that are not in project #785
Description
A duplication of #293 but it was closed by the author with no solution provided
For some reason datasources in workbooks can only be found by ID and can not be downloaded
ds = server.datasources.get_by_id("d5c9def5-61f0-49ce-a860-d688edf28f6e")
server.datasources.populate_connections(ds)
ds
>>> <tableauserverclient.models.datasource_item.DatasourceItem object at 0x000001D587581BB0>
path = server.datasources.download(ds.id)
>>>tableauserverclient.server.endpoint.exceptions.ServerResponseError:
>>> 404004: Resource Not Found
>>> Datasource "d5c9def5-61f0-49ce-a860-d688edf28f6e" could not be found
Also, if I retrieve all datasources from the server it's not there
temp_list = [ds for ds in TSC.Pager(server.datasources.get) if ds.id == "d5c9def5-61f0-49ce-a860-d688edf28f6e"]:
temp_list
>>> []

I think this question is asking about embedded data sources. These are published as part of the workbook, and cannot be downloaded separately - you have to download the workbook as a complete twbx file.

Hi @jacalata , Can you please check this again. Since as per the Tableau REST API documentation for Download Data Source, this method should download the datasource in .tdsx format and not twbx file.
Tableau REST API URL - https://help.tableau.com/current/api/rest_api/en-us/REST/rest_api_ref.htm#download_data_source
tdsx zip file contains the datasource extract which contains all the data extracted from backend database for that specific workbook.
Also the tableauserverclient method below is the python wrapper for the above API and its documentation also state the same.
tableauserverclient URL - https://tableau.github.io/server-client-python/docs/api-ref#datasourcesdownload
Downloads the specified data source in .tdsx or .hyper format..
but it is not working as per the REST API specification.

This was fixed in two stages:
fix_filename()to handle RFC 5987filename*=UTF-8''format inContent-Dispositionheaders, which addressed the main failure modecgimodule and clean up related dead code #1771): removed thecgimodule entirely, replacingcgi.parse_header()withemail.message.Message.get_filename(failobj="")— now returns an empty string gracefully when no filename is presentWill be fully resolved in v0.41.

Closing — this is fixed as of v0.41 for the "download fails when the datasource is not in a normal project" case.
Datasources.download(datasources_endpoint.py:235) delegates toDownloadableMixin._download_content(endpoint.py:338-381), which now parses theContent-Dispositionheader viaemail.message.Message.get_filename()— handles the RFC 5987filename*=UTF-8''form the server returns for personal-space and other non-project locations. Please open a fresh issue if you're still hitting a 404 on a supported TSC/Server version.
