Qlik Talend Products: tDataQualityRules component fails to refresh rules and receives "HTTP 400 Bad Request " error

[Soheb_Algur]

In Talend Studio 8.0 (version R2025‑05), tDataQualityRules component fails to refresh data quality rules defined in Talend Cloud Data Stewardship. When attempting to refresh, the UI remains unresponsive and does not load updated rules.

The Studio logs record an Unhandled event loop exception and a 400 Bad Request HTTP error when retrieving a rule artifact artifact .jar file from the rule repository.

 
Caused by: org.springframework.web.client.HttpClientErrorException$BadRequest: 400 Bad Request
<Resource>/eu-central-1-minio-production/repositories/<UUID>/rules/1753780XXXXX/rules-1753780XXXXX.jar</Resource>
<Code>InvalidRequest</Code>

Resolution

Please update rule to the latest version in all sub-jobs and use  TDC to download jar files.

In the URL field of tDataQualityRules component basic setting, updating it to https://tdc.eu.cloud.talend.com

Cause 

The error is caused by a malformed or stale artifact path to repository where Talend Studio is attempting to fetch a rule artifact .jar file from.

It is a known issue that cannot connect to TDS Gateway https://tds.us.cloud.talend.com/ to download jars
