Getting an error when trying to use terra.lcd.staking.delegations(delegator)

[amanusk]

I am getting an error when trying to use terra.lcd.staking.delegations(delegator);
This is the address I used in tequila:
https://tequila-fcd.terra.dev/staking/delegators/terra1xpjtwmemdwz053q4jxjx0ht4dtp25rc799deyf/delegations

Expected to receive the delegation state of the address.
Instead got a crash:
