Description

Error:

com.facebook.react.common.JavascriptException: TypeError: null is not an object (evaluating 'w.fastGwei'), stack:
saveCustomGasSelection@2989:9834

Technical Requirements

• Handle undefined fastGwei field. This is most likely caused by undefined basicGasEstimates, so may need to dig into why that is undefined.
• Properly handle/render condition where fastGwei is undefined.
• This issue lives in the CustomGas index.js file

Acceptance Criteria

• Hardcode either basicGasEstimates or fastGwei to be undefined and ensure component is gracefully rendering properly.
