Error using google.protobuf.Any

Sandbox: https://repl.it/repls/GleamingWhimsicalInformationtechnology

pbf fails to compile this proto

message RequestEnvelope {
    string correlationId = 1;
    string callPath = 2;
    google.protobuf.Any payload = 3;
}

with

./node_modules/pbf/compile.js:157
default:  throw new Error('Unexpected type: ' + field.type);
 
Error: Unexpected type: google.protobuf.Any
at compileFieldRead (./node_modules/pbf/compile.js:157:28)

Is it known that it's not supported or am I doing something wrong?

You may need to manually import the type.

https://github.com/protocolbuffers/protobuf/blob/master/src/google/protobuf/any.proto

[anri-asaturov]

@kjvalencik do you mean like copy and paste the any.proto content to my proto? because the file exists in ./google/protobuf folder relative to my proto

[kjvalencik]

You shouldn't need to copy if it's already there. Do you have an import line for it? Only paths are supported when importing in pbf.

[anri-asaturov]

@kjvalencik

option go_package = "go";

package wire;

import "google/protobuf/any.proto";

message RequestEnvelope {
    string correlationId = 1;
    string callPath = 2;
    google.protobuf.Any payload = 3;
}

this is the full file. The ./google/protobuf/any.proto file exists (otherwise I get ENOENT)

Ok so what i managed to figure out is that when proto is parsed, it looks like this

  syntax: 3,
  package: 'wire',
  imports: [ 'google/protobuf/any.proto' ],
  enums: [ { name: 'EnvelopeType', values: [Object], options: {} } ],
  messages: [
    {
      name: 'RequestEnvelope',
      enums: [],
      extends: [],
      messages: [],
      fields: [Array],
      extensions: null
    },
    {
      name: 'ResponseEnvelope',
      enums: [],
      extends: [],
      messages: [],
      fields: [Array],
      extensions: null
    },
    {
      name: 'Any',
      enums: [],
      extends: [],
      messages: [],
      fields: [Array],
      extensions: null
    }
  ],
  options: { go_package: 'go' },
  extends: []
}

Note the Any - it's in the root, like I defined it myself. But getType function expects Any descriptor to be nested in google:{ protobuf: {Any: ...}}

const path = field.type.split('.');
const ret = path.reduce(function(ctx, name) {
  return ctx && ctx[name];
}, ctx);

Did (@anri-asaturov) you find solution? I have same problem, but with google.protobuf.BytesValue (in wrapper.proto)?

[anri-asaturov]

@janch11 no, I had to fork/rewrite pbf to my needs since there was even more issues not aligning with my use case
