API Error Ora-20105 The directory id is not allowed to run the application

I am also getting the same error. if you have  the solution kindly share

​@kulind,

In order to troubleshoot this error it would be helpful to get the following details:

• package name
• release level of IFS Cloud in use
• user account in use to execute the package
• permissions, i.e. database roles and privileges, granted to the user account

The error means your bearer token is valid, but IFS cannot map the identity inside it to an active IFS user. Authentication at the IAM level succeeded; the failure is one step later when the IFS backend tries to resolve your token's directory ID to a real application user.
 

The most common cause is that the IAM client was not fully configured to create and activate an IFS service user.

Can you try below:
 

Go to Solution Manager > Users and Permissions > Identity and Access Manager > IAM Client and open the client you are using.
 

Make sure all four of these are enabled:

Service Accounts - Yes
Direct Access Grants - Yes
Create IFS Service User - Yes
Activate IFS Service User - Yes

When Create IFS Service User is enabled, IFS automatically creates a service user whose Directory ID matches the IAM service account name (service-account-<your_client_id>). If this was skipped during setup, the IFS user simply does not exist and every API call returns FUSRNULL.
 

Navigate to Solution Manager > Users and Permissions > Users,
find the newly created service user, go to User Permissions, and grant a permission set that includes access to the entities you need (e.g. Customer/AccountSet projections).

Obtain a fresh bearer token and retry your AccountSet GET call.
