Mounting adls gen2 from databricks RBAC issue

I am trying to mount my Gen 2 storage account in databricks. I have added permission of Storage blob data contributor to the storage account. But I am getting below error:
Invalid permissions on the specified KeyVault https://kvmigrationnew.vault.azure.net/. Wrapped Message: Status code 403, {"error":{"code":"Forbidden","message":"Caller is not authorized to perform action on resource.\r\nIf role assignments, deny assignments or role definitions were changed recently, please observe propagation time.\r\nCaller: name=AzureDatabricks;appid=123abcdbhjdllajddaddd;iss=https://sts.windows.net/984433r41f5ssadfgfsf/\r\nAction: 'Microsoft.KeyVault/vaults/secrets/getSecret/action'\r\nResource: '/subscriptions/xxxx-xxx-xxx/resourcegroups/rsggen2demo/providers/microsoft.keyvault/vaults/kvmigrationnew/secrets/clientid'\r\nAssignment: (not found)\r\nDecisionReason: 'DeniedWithNoValidRBAC' \r\nVault: kvmigrationnew;location=eastus2\r\n","innererror":{"code":"ForbiddenByRbac"}}}

Resource group: rsggen2demo

Code:

# Application (Client) Secret Key
authenticationKey = dbutils.secrets.get(scope="gen2mig",key="ClientSecret")

# Directory (Tenant) ID
tenandId = dbutils.secrets.get(scope="gen2mig",key="TenantID")

endpoint = "https://login.microsoftonline.com/" + tenandId + "/oauth2/token"
source = "abfss://" + adlsContainerName + "@" + adlsAccountName + ".dfs.core.windows.net/" + adlsFolderName

# Connecting using Service Principal secrets and OAuth

# Mount ADLS Storage to DBFS only if the directory is not already mounted
if not any(mount.mountPoint == mountPoint for mount in dbutils.fs.mounts()):
dbutils.fs.mount(
