TypeError: Cannot read properties of undefined (reading 'symbol')

I am running the smart router on Base mainnet.
When I run the code in the Readme, it works fine like the below screen shot.

However, if I change the tokens (ETH -> Clanker) I get this error.

./bin/cli quote --tokenIn 0x0000000000000000000000000000000000000000 --tokenOut 0x1bc0c42215582d5a085795f4badbac3ff36d1bcb --amount 1000000000000000000 --exactOut --minSplits 1 --protocols v2,v3,mixed --router alpha --chainId 8453   

TypeError: Cannot read properties of undefined (reading 'symbol')

How can I handle this?
