Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notification on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

WKC API must return a specific error messages

WKC API must return a specific error so VZ can pinpoint why an extract is failing

When the data profiling script is executed, we are receiving errors/ exceptions from the WKC API call intermittently.

The response error code that it returns is not sufficient to understand what it means.

An exception happens in one execution and does not happen in the next execution for the same set of schemas.

Exception code needs to be more explicit about what failed.

  • Requesting for a specific WKC error code and what it means. The standard API error codes are not sufficient

Please see below examples: provided in the Jira as well →

Executed CDL profile extraction on 5/16 17:03

  • got the following error → No resource found

Executed OVA extract on 5/20 15:50

  • This was the exception. We were told that this is a Gateway Timeout (502) issue

File "/apps/opt/application/wkc-scripts-master/wkc-scripts/scripts/", line 280, in get_asset_ids

raise Exception(asset_search_response.text)

Exception: (20211119_0901) x86_64

Executed on 5/27 and getting below exceptions:

  • OVA extract error

    • File "/apps/opt/application/wkc-scripts-master/wkc-scripts/scripts/", line 285, in get_asset_ids

    • raise Exception(asset_search_response.text)

    • Exception: (20211119_0901) x86_64

  • CDL extract error

    • File "/apps/opt/application/wkc-scripts-master/wkc-scripts/scripts/", line 51, in find_catalog_id

    • raise Exception(catalogs_list_request.text)

    • Exception: (20211119_0901) x86_64

The information provided to us was to use the below swagger document. Please see below

WKC apis and a list of response codes - swagger document

Data AssetsGET /v2/data_assets/{data_asset_id}

response codes section

The response that this shows are 4 codes. We cannot understand why it failed with a status of 400 or 500. IBM team said that the API can return 500 when the input data has a formatting/bad character. We cannot identify that by seeing 500 Internal Server errors.

We need deeper reason codes and exact messages.
