RequestError: Timeout: Request failed to complete in 15000ms

Issue: unable to set requestTimeout with configuration parameter for “mssql” dilect No matter whatever value is in requestTimeout parameter, the driver sets default value of “15000ms”. Hence, Timeout error occurs for all query that takes longer than 15s.

Application log is as follows:

Executing (default): SELECT [AnalysisTagID], [RefDate], [CategorySet], [AssetID], [Category] FROM [EMA_RiskAllocCategoriesView] AS [EMA_RiskAllocCategoriesView] ORDER BY [EMA_RiskAllocCategoriesView].[AssetID] OFFSET 0 ROWS FETCH NEXT 3 ROWS ONLY;

What are you doing?

sequelize is instantiated as follows where requestTimeout is set to 30s

const sequelize = new Sequelize(config.db.schema, config.db.username, config.db.password, {  
  "host": config.db.url,
  "dialect": "mssql",
  "dialectOptions": {
    "requestTimeout": 300000
  },
  pool: {
    max: 5,
    min: 0,
    acquire: 30000,
    idle: 10000
  }
});

A query that does full scan in a large table is run as follows:

EMA_RiskAllocCategoriesView.findAll({
    }).catch((err)=>{
      console.log("Error EMA_RiskAllocCategoriesView.getAll",err)
    });

To Reproduce Steps to reproduce the behavior:

1. Initiate sequelize with requestTimeout set to 30s
2. Use a query that takes longer than 15s
3. See error which says “Request failed to complete in 15000ms”

What do you expect to happen?

Not thow request timeout error for queries that run for 30s if sequelize is set to have requestTimeout of 30s.

What is actually happening?

Timeout Error for all query that takes longer than 15 s

Output, either JSON or SQL

Environment

Dialect:

• mssql

Dialect library version: tedious 6.1.2 Database version: mcr.microsoft.com/mssql/server:2017-latest (docker) Sequelize version: 5.8.7 Node Version: v12.3.1 OS: osx If TypeScript related: TypeScript version: XXX Tested with latest release:

• No

Self investigation. hard coded fix is to change the value of the following variable in “lib/connection.js” module of tedious library const DEFAULT_CLIENT_REQUEST_TIMEOUT = 15 * 1000;

@nash90: I had the same issue. Try doing this instead:

"dialectOptions": {
    options: { "requestTimeout": 300000 }
  },

For me in NodeJs with Mssql worked just this small change: just put outside of the options the field requestTimeout

const config = { user: ‘login’, password: ‘pass’, server: ‘10.11.24.15’, port: 1433, database: ‘base’, ‘requestTimeout’: 130000, options: { ‘enableArithAbort’: true, ‘idleTimeoutMillis’: 130000 },
