Gas estimatin fee error

[crux25]

On remix calling certain smart contract results to "Gas estimation fee error" which ultimately leads to a failed tx.

See screenshot below.

Hi Crux, this is the reply I got from Chainlink support about a question I asked about this issue.

the gas estimation error may not have to do with the infinite gas annotation. the infinite gas annotation doesnt AUTOMATICALLY mean it will be gas -expensive, rather it means that the data types being used are unbounded in size and therefore there may be infinite gas used in theory etc.

The gas estimation error often can arises due to incorrect configuration, contract reverts, etc or if your insurance contract is huge or something. Do you have transaction hash on sepolia of a failed transaciton that you can share? maybe we can take a look to debug what's failing

So I'm currently working to debug what is wrong, but no success yet. Will continue with it today.

@crux25 I have been able to solve this problem on my other side project. I think it was related to configuration problems since the example I worked on my side project was created in 2020, and I had to do lots of optimization. I'll work on the problem on the LinkiSwap tokenTransfer smart contract to try and resolve it too.

@crux25 This error is actually a configuration error and can be caused by a few things. For example, when calling a function, your Metamask is set to another network different from the one you were supposed to use.

It can also occur if you do not give the configuration router address, chainselector or Linktoken address.

Sometimes, switching Metamask chains and going back fixes the problem.

Sometimes, not having enough funds on the contract can also cause it.

It is not a major error, when it happens, just know to check the above scenarios.

It's a very crazy error and can be frustrating to fix.

The new smart contract that transfers data and tokens is free from such errors, if other configurations are cool.
