startBlock on arbitrum-rinkeby not working on hosted service

bug

What is the current behavior?
when I run the docker, LOCAL version of a graph-node and for the networking arbitrum-rinke
by it allows me to specify startBlock: 13940833 and works properly. When I use the HOSTED service it errors out saying that the block does not exist on the Ethereum network. I think what may be going on is your startBlock check is not network sensitive.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.
Please try to deploy anything to the hosted service on the arbitrum-rinkeby network with startBlock: 13940833 specified and you will have the error.

What is the expected behavior?
Expected behavior is the hosted service does not error out and starts indexing at the start block on arbitrum-rinkeby
