Missing property 'token' on type 'AbstractCredentialsResponseElement'


I tried to use credentialVaultClient to retrieve a token stored in the credentials vault. It seems like the property token is missing on the type AbstractCredentialsResponseElement. Also, I need to copy the response to get the token.


	private getToken = () => {
		const resp = credentialVaultClient.getCredentialsDetails({
			id: dynatraceConfig['API_TOKEN'][this.environmentId][this.env],
		const respCopy: any = { ...resp };
		return respCopy.token;


This is my package.json:


"dependencies": {
    "@dynatrace-sdk/app-environment": "^1.0.0",
    "@dynatrace-sdk/app-utils": "^0.2.2",
    "@dynatrace-sdk/client-classic-environment-v2": "^1.1.0",
    "@dynatrace-sdk/client-query": "1.2.0",
    "@dynatrace-sdk/error-handlers": "1.1.0",
    "@dynatrace-sdk/navigation": "1.0.0",
    "@dynatrace-sdk/user-preferences": "1.0.0",
    "@dynatrace/strato-components-preview": "0.97.1",
    "@hookform/resolvers": "^3.1.1",
    "joi": "^17.9.2",
    "react": "^17.0.0",
    "react-dom": "^17.0.0",
    "react-hook-form": "^7.45.1",
    "react-router-dom": "^6.4.1"


Please advise. Thanks.

Hi @StephenLHChancredentialVaultClient.getCredentialsDetails is an asynchronous function, which means it returns a Promise. To properly handle this, you should use async/await, something like this should work:


import {
} from "@dynatrace-sdk/client-classic-environment-v2";


private async getToken = () => {
  const resp = await credentialVaultClient.getCredentialsDetails({
    id: dynatraceConfig['API_TOKEN'][this.environmentId][this.env],
  }) as CredentialsDetailsTokenResponseElement;

  return resp.token;


Notice the keywords async in the function declaration and await right before the call to the credentials vault. Besides that, notice that I added a type assertion as CredentialsDetailsTokenResponseElement, which allows you to properly access resp.token. The reason for this is that depending on the type of the credential, the response will be of a concrete type or another (instead of just AbstractCredentialsResponseElement), containing different sets of fields. You can see all the different types in the SDK reference in the Dynatrace Developer portal.
