SparkException: There is no Credential Scope.

Hi 🙂

I am new to databricks and trying to connect to Rstudio Server from my all-purpose compute cluster.

Here are the cluster configuration:

Policy: Personal Compute

Access mode: Single user

Databricks run time version:

13.2 ML (includes Apache Spark 3.4.0, Scala 2.12)

Following the instruction here, I am trying to run the codes both with sparlyr and sparkR.

Sparklyr

> library(sparklyr)
> sc <- spark_connect(method = "databricks")

However, I receive the below error:

Error in value[[3L]](cond) :
