  One strategy to handle the 'graphql cannot return null for non-nullable field' error in cryptocurrency applications is to thoroughly analyze the GraphQL schema and identify the non-nullable fields causing the error. Once identified, you can either modify the schema to make these fields nullable or ensure that the necessary data is always available for these fields.

  Dealing with the 'graphql cannot return null for non-nullable field' error in cryptocurrency applications can be frustrating, but there are ways to tackle it. One approach is to use GraphQL resolvers to handle the error. By implementing custom resolvers, you can check if the required data is available and return a default value or an appropriate error message if it's not. Another option is to use GraphQL unions or interfaces to handle nullable fields, allowing for more flexibility in the data returned.
