Thanks Sofie. That seems a Display bug cause i had to change my SQL script transform and change my first name 1st letter by an A instead of a Y. After i could retrieve My asset.

Hi.

In the lesson #18 I’m not getting why the query bellow is returning 0 rows, since I do have cdm_assets.externalId equals to “Leonardo1987:23-1ST STAGE COMPRESSOR-PH”, for example. And there is the asset “23-1ST STAGE COMPRESSOR-PH”.

SELECT
workpackage_desc AS description,
to_timestamp(completion_time/1000) AS endTime,
to_timestamp(start_time/1000) AS startTime,
concat('Leonardo1987:',key) AS externalId,
array(node_reference("cdf-fundamentals", CAST(cdm_assets.externalId as STRING))) as assets
  
from IFSDB.maintenance as t1
join cdf_data_models("cdf_cdm", "CogniteCore", "v1", "CogniteAsset") as cdm_assets
on cdm_assets.externalId = concat('Leonardo1987:',t1.func_loc)

Hi ​@leonard.cruz 

I don’t know why there is nothing showing up from the preview. But I see that you did run it successfully. And when I check your CogniteActivites, they are liked to the CogniteAsset. So you have but everything correctly.

Part 2 - Hands-on / Lesson 11 of 27 (Verification of ingestion)
Oddly, the ‘Starts with’ filter does not show my newly-transformed Assets (first screenshot) but the general Search does. Perhaps just an odd quirk.

working thru Cognite Data Fusion Fundamentals: Part 2 - Hands-on

I can preview the SQL, but on lesson 10, to run, I get this error with my asset Dominick1970:

[DATAMODELS] Request with id a6de5f06-0af4-949c-846c-cafd08bc8824 to https://api.cognitedata.com/api/v1/projects/cdf-fundamentals/models/instances failed with status 403: Not allowed to perform instances action: READ.

I’ve logged off and back of thinking my credentials haven’t full set, but after many trys still the same error.

Any thoughts on how to resolve this?
