It appears that all token data (from whet I’ve tested) is missing before 2021-10-18 on BSC.
For example…
Token : SpaceCowBoy
Contract : 0x0d36cc179019db9a65aa3b85db59e4bb52df0b12
Exchange: pancakeswapv2
Pair Address : 0x8d5fbc212fc28da7b2682cfbd5ad2f42b8fd5540

… “message”: “No reserves data found for pair”

… “reserve0”: “5669588467242958563554”
… “reserve1”: “371563655890108618389”
I’ve tested around 20 tokens - and it appears to effect them all.
