UnhandledPromiseRejectionWarning for gas limit

[tobyjaguar]

ran into this one, and I don't think it is me as this call is wrapped in a try/catch.

UnhandledPromiseRejectionWarning: Error: cannot estimate gas; transaction may fail or may require manual gas limit...

not sure how pesky this is, if it will take down the process as I get this at the end of the trace:

DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

I need at least a code snippet to go off of. :p

ha, fair!

I am actually getting a lot of there Unhandled promise rejections, not sure if they are coming from ethers, but they seem to hit when I am making a transaction.

I think the call that is doing it is:

contract.catchDataCall(requestId, price, signature, { nonce: ++txCount, gasLimit: 12487794 }); // gas limit for kovan

with some errors:

(node:16995) UnhandledPromiseRejectionWarning: Error: Transaction cost exceeds current gas limit. Limit: 12487794, got: 30000000. Try decreasing supplied gas.

The error indicates you were exceeding the block gas limit. You need to reduce the gas you are passing along. :)
