gRPC 3 INVALID_ARGUMENT vs 15 DATA_LOSS
Both gRPC 3 (INVALID_ARGUMENT) and 15 (DATA_LOSS) belong to the gRPC Status Codes category. 3 indicates that the client specified an invalid argument. This indicates arguments that are problematic regardless of the state of the system. Meanwhile, 15 means that unrecoverable data loss or corruption has occurred.
Description
The client specified an invalid argument. This indicates arguments that are problematic regardless of the state of the system.
When You See It
A request field failed validation — for example, a negative page size, a malformed email, or a required field left empty.
How to Fix
Inspect the request payload and fix the invalid field. Check the API documentation for expected formats and constraints.
Description
Unrecoverable data loss or corruption has occurred.
When You See It
Critical data was lost or corrupted — for example, a checksum mismatch during transmission or an unrecoverable storage failure on the server.
How to Fix
Investigate the data integrity failure immediately. Restore from backups if available, and check for hardware failures or network corruption in the data path.
Key Differences
gRPC 3: The client specified an invalid argument. This indicates arguments that are problematic regardless of the state of the system.
gRPC 15: Unrecoverable data loss or corruption has occurred.
You encounter 3 when a request field failed validation — for example, a negative page size, a malformed email, or a required field left empty.

When to Use Which
For 3 (INVALID_ARGUMENT): Inspect the request payload and fix the invalid field. Check the API documentation for expected formats and constraints. For 15 (DATA_LOSS): Investigate the data integrity failure immediately. Restore from backups if available, and check for hardware failures or network corruption in the data path.
