ORACLE: Stored procedure issue using "raw()"

Knex version : 0.12.6

I get what it seems to be a Bluebird error when I try to execute an Oracle stored procedure using raw() :

knex.raw("BEGIN MY.STORED.PROCEDURE(?, ?, ?); END;",
    [
        { "dir": oracledb.BIND_IN, "type": oracledb.NUMBER, "val": 13036 },
        { "dir": oracledb.BIND_OUT, "type": oracledb.NUMBER },
        { "dir": oracledb.BIND_OUT, "type": oracledb.NUMBER }
    ]).then((result) => {
        console.log("Success : " + JSON.stringify(result));
    }).catch((err) => {
        console.log("Error : " + err);
    });

This results in the error :

Error : TypeError: BEGIN MY.STORED.PROCEDURE(:1, :2, :3); END; - expecting an array or an iterable object but got [object Null]

If I debug, I see that the request works, Oracle response is correct. Here’s a screenshot of a breakpoint in file node_modules/knex/lib/dialects/oracledb/index.js, line 162 :

The err is null, there are no rows or resultSet in the results object but a outBinds array, containing the OUT parameters of the stored procedure call.

The error actually occures when line 205 is reached :

resultResolve(results);

Not a “fix”, but what we do now is to use a raw connection taken from Knex’s connection pool when we need to use a stored proc with out parameters :

export async function withRawConnection(action: (connection: any) => Promise<any>): Promise<any> 
{
    let connection = await client.acquireConnection();
    try {
        return await action(connection);
    }
    finally {
        try {
            await client.releaseConnection(connection);
        }
        catch (err) {
            logger.warning(err, `Unable to release a raw oracledb connection`);
        }
    }
}

Hi!

Any update in this? I’m having the same problem using knex and oracledb.

Any workaround to solve this?
