chainType: mainchain .contractMap.TFuelTokenBank: undefined

[muratso]

I'm seeing the following error on the crawler once in a while. Is this expected? Is there some missing config?
chainType: mainchain .contractMap.TFuelTokenBank: undefined. I'm using the latest commit from master 79a80c9

and here's my config file

It's worth mentioning that I was syncing the crawler from scratch and we're currently at the block height 12689271.
