  At BYDFi, we have seen this error occur in some cases. One possible reason for this error is when the API response does not include the 'code' property for a particular cryptocurrency. This can happen if there are inconsistencies or errors in the data provided by the API. To fix this error, you can check the API response and verify if the 'code' property is present for the cryptocurrency you are trading. If it is missing, you may need to consider using a different API or contacting the API provider for further assistance. Another possible reason for this error is when there is an issue with the connection between the trading platform and the API. This can result in incomplete or undefined data being received, leading to the 'cannot read properties of undefined' error. To resolve this, you can try refreshing the connection or restarting the trading platform. If the issue persists, it's recommended to reach out to the technical support team of the trading platform for troubleshooting steps. In summary, the 'cannot read properties of undefined (reading 'code')' error in cryptocurrency trading can occur due to uninitialized variables, incorrect property names, issues with API data, or problems with the trading platform. By carefully reviewing your code, verifying API responses, and ensuring a stable connection, you can minimize the occurrence of this error and have a smoother trading experience.
