Run time issues with Ballerina Integrator

Question

I am trying to run the sample File Integration with FTP which is given by Ballerina Integrator.

While running the service i am facing same issue each and every time.

I have installed Ballerina Integrator only. I have done uninstall and installation freshly after that also Same issue.

Please help me.

Answer 1

Just install Ballerina Integrator alone which is packed with Ballerina 1.0.2 so no need to install Ballerina again or separately. From VSCode why output is not coming means,VSCode's market place all are upgraded with latest version.

Locally installed "BI with Ballerina" is lower version, In VSCode "BI with Ballerina" is latest one. Mismatched version is the main problem which i was faced.

Answer 2

I could successfully run the sample with following configurations. (sample data are given). Here I have used a Secured FTP server to do the configuration.

listener ftp:Listener dataFileListener = new({
    protocol: ftp:SFTP,
    host: "18.156.78.137",
    port: 22,
    secureSocket: {
        basicAuth: {
            username: "cloudloc",
            password: "fsf#$#213"
        }
    },
    path: "/clouddir/"
});

ftp:ClientEndpointConfig ftpConfig = {
    protocol: ftp:SFTP,
    host: "18.156.78.137",
    port: 22,
    secureSocket: {
        basicAuth: {
            username: "cloudloc",
            password: "fsf#$#213"
        }
    }
};

Make sure you set the path parameter correctly in the dataFileListener. Without this parameter I could reproduce your attached error. Once this is correctly configured you would get a log printed like follows.
