Configured environment is not supported yet

When I am trying to deploy my app using rc-apps deploy , I get the following error:

Is this error occuring due to a bug within RC or the library node-fetch ?My current code is:

import {
    IHttp,
    IModify,
    IRead,
} from '@rocket.chat/apps-engine/definition/accessors';
import fetch from 'node-fetch';
import {
    ISlashCommand,
    SlashCommandContext,
} from '@rocket.chat/apps-engine/definition/slashcommands';

 export class n implements ISlashCommand {
    public command = 'n';
    public i18nParamsExample = '';
    public i18nDescription = '';
    public providesPreview = false;

    public async executor(context: SlashCommandContext, read: IRead, modify: IModify, http: IHttp): Promise<void> {

      const supply = '{"fields": {"project": {"key": "TEST"},"summary": "TEST the API","description": "testing API","issuetype": {"name": "Bug"},"customfield_11050": "idk."}}'
      const response = await fetch('http://localhost:3000/', {
        method: 'post',
        body: JSON.stringify(supply),
        headers: {'Content-Type': 'application/json'}
        });
      const data = await response.json();

      console.log(data);
};
};

My tsconfig.json file looks like this:

{
"compilerOptions": {
    "target": "es2017",
    "module": "commonjs",
    "moduleResolution": "node",
    "declaration": false,
    "noImplicitAny": false,
    "removeComments": true,
    "strictNullChecks": true,
    "noImplicitReturns": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    },
"include": [
    "**/*.ts"
    ]
}

Check this -

change tsconfig.json file

"compilerOptions": {
"target": "es2017",
"module": "commonjs",
.......
},

to this

"compilerOptions": {
"target": "esnext",
"module": "commonjs",
..........
},

Check this -

change tsconfig.json file

"compilerOptions": { "target": "es2017", "module": "commonjs", ....... },

to this

"compilerOptions": { "target": "esnext", "module": "commonjs", .......... },

Unfortunately, the same error occurs still. Any other ideas please?
