No AH blocks found for some RC blocks

[Imod7]

Why do some responses from

/block/{blockNumber}?useRcBlock=true

return empty results on Westend (Relay chain)?

For instance, block 27205584 appears to have no associated Asset Hub blocks.

[Imod7]

Not every Relay Chain block contains a corresponding Asset Hub block.

In the case of RC block 27205584, no Asset Hub blocks are present because:

• An Asset Hub block was produced at RC block 27205583
• The subsequent Asset Hub block was generated at RC block 27205585
