SQL error
After the request from the client React js input databases the database server stops and writes the following message: sqlMessage: 'sql parameter is mandatory', sql: null, fatal: false, errno: 45049, sqlState: 'HY000', code: 'ER_UNDEFINED_SQL'
What is the problem?
Answer Answered by Ian Gilfillan in this comment.
Missing sql parameter? To expand, the question provides almost no useful context that could help in answering the question beyond the error message. See for example https://opensource.com/life/16/10/how-ask-technical-questions
