# INVALID_INDEX

**INVALID_INDEX** is a subcondition of the DELTA_STREAMING_SKIP_OFFSETS_INVALID_OFFSET_RANGE Error Class|DELTA_STREAMING_SKIP_OFFSETS_INVALID_OFFSET_RANGE error class in Databricks. It occurs when a streaming offset’s index does not match the expected base index during a skip‑offsets operation for a Delta source. ^[delta_streaming_skip_offsets_invalid_offset_range-error-condition-databricks-on-aws.md]

## Error Message

When this subcondition is triggered, the error message states:

```
Offset index must be `BASE_INDEX (<baseIndex>)`.
```

The placeholder `<baseIndex>` represents the required index value that the offset should have. The actual offset index provided is incorrect. ^[delta_streaming_skip_offsets_invalid_offset_range-error-condition-databricks-on-aws.md]

## Context

The `INVALID_INDEX` error appears as one of the possible sub‑conditions under the broader `DELTA_STREAMING_SKIP_OFFSETS_INVALID_OFFSET_RANGE` error class (SQLSTATE 42616). The full error message for the class is:

```
Invalid skip offset range for Delta source range=[<startOffset>, <endOffset>). Fix this offset range and try again.
```

Other subconditions include `EVENT_TIME_PRESENT` (offsets must not have event time) and `INITIAL_SNAPSHOT` (offsets must not be initial snapshot offsets). ^[delta_streaming_skip_offsets_invalid_offset_range-error-condition-databricks-on-aws.md]

## Resolution

To resolve the `INVALID_INDEX` error, ensure that the offset index in the skip‑offsets request matches `BASE_INDEX` with the correct base index value. The offset range must conform to the expected format for the Delta streaming source. ^[delta_streaming_skip_offsets_invalid_offset_range-error-condition-databricks-on-aws.md]
