  One possible solution is to check if the query being executed is returning null values for non-nullable fields. This can be done by examining the query and the corresponding database schema. If any non-nullable fields are found to be returning null values, the query or the database schema should be modified to ensure that these fields always have a valid value. Another troubleshooting step is to verify the data being passed to the query. If the data is not properly formatted or contains invalid values, it can cause the 'cannot return null for non-nullable field query' error. Make sure that the data being passed to the query is valid and correctly formatted. If the above steps do not resolve the issue, it is recommended to seek assistance from the support team of the cryptocurrency application. They may have specific troubleshooting steps or updates that can fix the error. Remember to always keep your cryptocurrency application up to date with the latest version, as updates often include bug fixes and improvements that can resolve such errors.
