Encoding errors

[krlwlfrt]

I just updated my project to Node.js 12 (newest LTS), NWRFC 750P_7-70002752 (newest available version to download) and node-rfc 2.1.0 (current version).

I saw strange symbols in the output of our function module. So I tried the function module STFC_STRUCTURE, that is also mentioned in the readme.

Below is the JSON representation of the returned structure. What could be the cause of this?

The 2.2.0 release provides the fix

[krlwlfrt]

Unfortunately I can not confirm this. I just installed node-rfc 2.2.0. The following is the output of client.environment.

{
  platform: { name: 'linux', arch: 'x64', release: '5.8.14-arch1-1' },
  env: { SAPNWRFC_HOME: '', RFC_INI: '' },

    brotli: '1.0.9',
    ares: '1.16.0',
    modules: '72',
    nghttp2: '1.41.0',
    napi: '7',
    llhttp: '2.1.2',
    http_parser: '2.9.3',
    openssl: '1.1.1g',
    cldr: '37.0',
    icu: '67.1',

  },
  noderfc: {
    version: '2.2.0',
    nwrfcsdk: { major: 7500, minor: 0, patchLevel: 7 }
  }
}

The output of the returned structure looks different but still wrong.

Which Linux distro do you use?

Could you please post the output of ls -la node_modules/node-rfc/lib/binding ?

You can also try the build from source.

[krlwlfrt]

I have to apologize. I should have done a clean install previously. That's what I did now. Removed node_modules and package-lock.json and installed again. It's working now. Thank you!

Does the v2.2.0 release also include the fix for #165 #176?

[bsrdjan]

Yes, the 2.2.0 and future releases are built as described here: node-rfc/#176/#issuecomment-703690345/
