Known Issues
Vantage ModelOps
| Key | Description |
|---|---|
| VMO - 1832 | The evaluation job for BYOM (except Python/R) with custom metrics fails. Workaround: Cannot evaluate BYOM (except Python/R) with custom metrics but can be evaluated using default metrics. While importing the default metrics can be selected for monitoring. Deployments: Lake on Azure| GC| AWS |
| VMO - 1827 | The evaluation job fails for BYOM DataRobot with error - ValueError: Classification metrics can't handle a mix of binary and unknown targets. Workaround: None. Cannot evaluate BYOM DataRobot. Deployments: Lake on Azure| GC| AWS |
| VMO - 1814 | While running a compute statistics job for BYOM model in Demo project (pre-loaded ModelOps project), it fails with error - categorical_features = f for f in feature_names if feature_summaryf.lower()] == 'categorical'] KeyError: 'numtimesprg' Workaround: Change database to td_modelops in the dataset template and for all (dataset template and datasets) SQL queries add the database as td_modelops. (Only for the Demo project) Example - Change SELECT * FROM pima_patient_features to SELECT * FROM td_modelops.pima_patient_features Deployments: Lake on Azure| GC| AWS |
| VMO - 1791 | Validating a training dataset while importing a BYOM fails with error - Cannot read properties of undefined (reading 'dropTableSql'). Workaround: None. The user cannot validate the training dataset and prediction expression. Deployments: Lake on Azure| GC| AWS |
| VMO-1747 | ModelOps provisioning could fail due to Private DNS timeout after 5 minutes. Workaround: Delete ModelOps and retry ModelOps provisioning. Deployments: Lake on AWS |
| VMO-1716 | While importing a BYOM and generating a prediction expression, the expressions do not list out and the loading icon shows up. The error message can be - 'Cannot convert undefined or null to object'. Workaround: Instead of generating a prediction expression, the user can manually enter the prediction expression. Example - CAST(CAST(json_report AS JSON).JSONExtractValue('$.predicted_HasDiabetes') AS INT). The prediction expression cannot be validated Deployments: Lake on Azure| GC| AWS |
User Defined Functions
| Key | Description |
|---|---|
| UDF - 1709 | BYOM functions may fail after a database restart. This is due to a problem with UDF containers being out of sync. Workaround: None. Submit a case from Support Portal to engage Teradata Support for assistance. Deployments: Lake on AWS |
| UDF - 1427 | It was discovered that there are issues in supporting more than one third party UDF solutions, including the following:
Workaround: There is no workaround to install more than one third party UDF solutions until this issue is resolved. If running into any issues, open a case from Support Portal to engage Teradata Support for assistance.
Deployments: AWS is the only platform on Lake supporting more than one third-party solution. |
OptToolsCloud
| Key | Description |
|---|---|
| TCOPTT-1012 | In VantageCloud Lake, when upgrading to the August 2024 release or later, if the PDCR history table PDCRDATA.AcctgDtl_Hst, Acctg_Hst, MonitorSession_Hst, TDWMThrottleStats_Hst or TDWMUtilityStats_Hst contains data (e.g., from a previous migration), then it will not be converted to an OFS table and the table's corresponding collection job will not run. Workaround: Run SQL statements to rename the existing table and create a new empty table in OFS. Submit a case from Support Portal to engage Teradata Support for assistance.

Open Table Format
| Key | Description |
|---|---|
| OTF-3306 | Insert Statement Fails with "Index Out of Bounds" for Iceberg/DeltaLake Unity. Workaround: Use all lowercase for both the table column names and the PARTITIONED BY clause. Problem query:
Workaround for this issue:
If you use uppercase letters for column names in the CREATE TABLE statement or the PARTITIONED BY clause, it will result in an error. So, for a workaround, always use lowercase column names in both the CREATE TABLE statement and the PARTITIONED BY clause

| OTF-3207 | The issue was seen when a Teradata Stored Procedure (TDSP) is created prior to 20.00.25.14 and is then called on a later release. In this case, Failure 7551 may return. The issue could also be seen when a table with Partitioned Primary Index (PPI) is created prior to 20.00.25.14 and is then used in a SELECT statement on a later release. Workaround: For a TDSP, recompile the TDSP before calling it. For a PPI table, revalidate the table before using it in a DML. Deployments: Lake on Azure| GC| AWS |
| OTF-3206 | DeltaLake Glue query fails with TD_OTFDB.TD_DELTA_READ: Provider for class javax.xml.stream.XMLInputFactory cannot be created. Workaround: None. Submit a case from Support Portal to engage Teradata Support for assistance. Deployments: Lake on AWS |
| OTF-3171 | Intermittent failures with mixed workload on AWS OTF queries. Workaround: Restart Java OTF UDF Server. Submit a case from Support Portal to engage Teradata Support for assistance. Deployments: Lake on AWS |
Fixed Issues
| Key | Description |
|---|---|
| OTF-3023 | Intermittent issue where OTF query cannot open the input stream. Workaround: Restart Java OTF UDF Server. Submit a case from Support Portal to engage Teradata Support for assistance. Deployments: Lake on AWS |
