In the middle of building stack the provider assumes a different role ( or provider is switched to different account, Eg: below code

provider = Provider(
        resource_name="different_account",
        region="eu-west-1",
        assume_role=ProviderAssumeRoleArgs(role_arn=role_arn),
    )
 BucketObject( resource_name=f"{name}-glue-job-script",
            opts=ResourceOptions(depends_on=[self._rolePolicy], provider=provider),
            bucket=destination_bucket.name,
            key=f"glue-job-scripts/{glue_script.split('/')[-1]}",
            source=FileAsset(glue_script))
Fails while doing above operation and following error occurs - Access denied error

aws:s3:BucketObject test-ab40dc-glue-job-script creating failed '
'Diagnostics:'

'AccessDenied: Access Denied'

        provider = Provider(
            resource_name="test-provider",
            assume_role="arn:aws:iam::123456789012:role/test-role",
        )

            raw_history_bucket=raw_history_bucket,
            tagger=self.tagger,
            provider=provider)
        print(test_pipeline._curatedBucket._providers)
