Get blocks (range) failed

Code

RPC/BLOCK/GET_BLOCKS_FROM_TO_FAILED

What it means

The client attempted to read a range of blocks from the contract, but the query failed.

When it happens

• Fetching a range of blocks from the chain fails.

Typical scenarios:

• Range is too large (timeout / heavy query)
• Node/transport failure
• Contract query failure

How to handle

• Include from and to in meta for diagnosis.
• Consider splitting into smaller ranges if this fails frequently.
