Sync request errors
These errors occur during sync planning, before Hightouch sends any data to the destination. They typically indicate a problem with your model, primary key, or warehouse configuration.| Error code | What it means | How to resolve |
|---|---|---|
DUPLICATE_COLUMNS_DETECTED | Your model query returns duplicate column names. | Alias columns in your model SQL so every selected field has a unique name. |
NON_UNIQUE_PRIMARY_KEY | The selected primary key contains duplicate values. | Update your model so each row has a unique identifier. If you’re using a SQL model, add a DISTINCT clause or GROUP BY on the key column. |
UNSUPPORTED_PRIMARY_KEY_TYPE | The primary key’s data type isn’t supported for this sync path. | Cast the primary key to a supported type (typically VARCHAR or INTEGER) in your model SQL. |
QUERY_COLUMN_MISSING | A column referenced in your sync configuration no longer exists in the model query results. | Refresh the model schema in Hightouch and update your field mappings to use valid columns. |
WAREHOUSE_TABLE_MISSING | A warehouse table required for sync planning doesn’t exist. | Confirm the table still exists in your warehouse and that the model points to the correct schema and table name. |
PREVIOUS_SYNC_RUN_OBJECT_MISSING | Stored objects from the previous sync run are missing, usually because cached plan data expired. | Retry the sync. If it persists, trigger a full resync to rebuild sync state. |
REMOVE_PLAN_INCOMPLETE | Backfill or removal planning couldn’t complete during a planner transition. | Retry the sync after a few minutes. If it continues, . |
REMOVE_RETRY_CHANGED_COLUMN_TYPES | Rejected-row removal retries are unsafe because model column types changed between runs. | Refresh your model schema and trigger a full resync from a consistent state. |
SORT_RAN_OUT_OF_DISK_SPACE | Sorting rows exhausted available disk space. | Narrow the model to reduce row volume, or for infrastructure help. |
UNSPECIFIED | Hightouch couldn’t classify the failure into a more specific code. | Use the live debugger and warehouse sync logs to identify the root cause. |
Destination errors
Generic destination errors
These errors can occur with any destination. They indicate a problem with authentication, rate limits, or the destination’s availability.| Error code | What it means | How to resolve |
|---|---|---|
DESTINATION_INVALID_GRANT | The destination’s authorization grant expired or was revoked. | Reconnect the destination in Hightouch to refresh authorization. |
DESTINATION_INVALID_CREDENTIALS | The destination credentials are invalid. | Verify the username, password, token, or secret configured for the destination. Reconnect if needed. |

These errors occur when training or running predictive trait models. They indicate a problem with training data, event configuration, or warehouse access.| Error code | What it means | How to resolve |
|---|---|---|
NO_USERS_IN_INPUT_FILE | The training audience returned no users. | Check that the parent audience or model query returns rows before training starts. |
NO_USER_ROWS_AFTER_FILTERS | Users were present initially, but predictive filters removed all of them. | Loosen the filters or verify that event and property conditions match real data. |
NO_TRAINING_DATA_FILES | Hightouch couldn’t generate the training dataset. | Confirm that the configured events return data and the event model is queryable. |
LABEL_FREQUENCY_TOO_LOW | There aren’t enough examples of the target outcome to train the model reliably. | Increase the lookback window, reduce filters, or choose a higher-volume outcome event. |
NO_POSITIVE_EXAMPLES | The training data contains zero positive examples of the target event. | Check that the outcome event is occurring for users in scope. |
TRAINING_MATRIX_DOWNLOAD_FAILED | An internal failure occurred while retrieving the training artifact. | Retry the run. If it persists, — this is typically not customer-fixable. |
NO_KEY_EVENTS | No feature-generation events are configured. | Add at least one event input in the predictive trait configuration before retraining. |
EVENT_MODEL_MISCONFIGURED | The event model configuration is invalid. | Confirm the event model exists, has a valid primary key, and includes all referenced columns. |
EVENT_QUERY_FAILED | Hightouch couldn’t query event data from the warehouse. | Check warehouse permissions, model SQL, and whether the referenced tables still exist. |
SOURCE_ACCOUNT_LOCKED | The warehouse user account is locked. | Wait for the lockout to clear, or have your warehouse admin re-enable the account. |
UNKNOWN_EVENT_IN_FILTER | A predictive filter references an event Hightouch can’t resolve. | Check for renamed, deleted, or misconfigured events in the predictive trait setup. |
INVALID_EVENT_PROPERTY_CONDITION | An event-property filter is malformed. | Verify the filter syntax and confirm you’re using valid string property names. |
NO_EVENT_DATA_FILES | No event data was produced for training or inference. | Confirm the configured events have recent data and event pulls are succeeding. |
TRAINING_ERROR | An internal training failure occurred. | Retry once. If it repeats, . |
CACHED_EVENT_PULL_DISABLED | A required event pull is disabled. | Re-enable the event pull in your schema configuration and rerun the predictor. |
MALFORMED_EVENT_DATA | Numeric event fields contain invalid values. | Clean the source data so numeric columns contain only valid numbers (no strings, nulls in numeric-only fields, etc.). |
MODEL_QUERY_FAILED | Hightouch couldn’t query the parent model data needed for the run. | Check that the parent model still exists and all referenced columns are present. |
