Any type usage help

[gkyildirim]

I am trying to figure out how to use Any type. I could not find an example nor my primitve attempts to define provider in appl.module.ts (with the help of Copilot) succeed.

May I ask how to use Any type?

If I do not define anything in app.module.ts I have this error:

core.mjs:8506 ERROR Error: Uncaught (in promise): Error: Message pool is required to cast Any to JSON

If I define something like this in app.modules.ts

 export function grpcMessagePoolFactory() {
 const messagePool = new GrpcMessagePool([]);
 messagePool.add([BoolValue, UInt64Value, FloatValue, StringValue, Timestamp]);
 return messagePool;
}

@NgModule({
 providers: [{ provide: GrpcMessagePool, useFactory: grpcMessagePoolFactory }],

I have this error:

    ```

My angular version is 15.1 if it matters.

Hello,

I apologize if I am asking the wrong question at the wrong place.

Thanks for the hard work.

Hi, you get this error because some of your code attempts to cast the message that contains Any to JSON.

You would need to adapt this code to pass message pool as a parameter to this method.

The most common reason is you use the standard logger that attempts to cast to JSON.

Try to disable the logger and check if the error is gone or adapt the place where you call toProtobufJSON method
