I built a Docker container that runs locally without error. When I deploy to AWS Fargate, the container runs, but throws runtime Javascript errors that don't appear when running locally. For example:
const fcl = require( '@onflow/fcl' );
const storefrontAddress = 0x9a0766d93b6608b7;
const eventOfferMade = `A.${ fcl.sansPrefix( storefrontAddress ) }.SaleOfferAvailable`;
This does not throw an error when the container is run locally, but throws n.replace is not a function when the container runs on Fargate. fcl.sansPrefix expects a String, not a hex number, and throws the error. I can coerce the number to a string as follows and it will run on Fargate:
const eventOfferMade = `A.${ fcl.sansPrefix( String.toString( storefrontAddress )) }.SaleOfferAvailable`;
Is this container somehow shifting into "use strict" mode? Is it using a different Javascript engine on Fargate? Is there a kernel dependency that could cause something like this?
Insights appreciated! Thanks!
