Calling `DBI::dbConnect(odbc::databricks())` a second time fails with `Error in driver_config$path ` on MacOS

[benesom]

Establishing a odbc connection works as expect for

args <- list(
  odbc::databricks(),
  auth_accesstoken = token,
  workspace = workspace,
  authMech = 11,
  auth_flow = 0,
  HTTPPath = httppath
)
conn <- do.call(DBI::dbConnect, args)

> conn
<OdbcConnection> Spark SQL
  Database: foundata_investigations_bronze_prd
  Spark SQL Version: 3.5.0

However, trying to "re-connect" to the cluster fails

> do.call(DBI::dbConnect, args)
Error in driver_config$path : $ operator is invalid for atomic vectors

The traceback points at odbc:::configure_simba, which was introduced in odbc v.1.6.0

   {

       .valueClassTest(ans, "DBIConnection", "dbConnect")
   }, generic = structure("dbConnect", package = "DBI"), package = "DBI", 
       group = list(), valueClass = "DBIConnection", signature = "drv", 
       default = NULL, skeleton = (function (drv, ...) 
       stop(gettextf("invalid call in method dispatch to '%s' (no default method)", 
           "dbConnect"), domain = NA))(drv, ...)))(new("DatabricksOdbcDriver", ), 
       auth_accesstoken = "xxxx", 
       workspace = "xxxx", 
       authMech = 11, auth_flow = 0, HTTPPath = "xxx")

Installing

devtools::install_github("https://github.com/r-dbi/odbc", ref = "v1.5.0")

and re-running the previous example works as expected. That is, calling

do.call(DBI::dbConnect, args)

a second time will return a odbc connection. The error does not occur on linux, as a consequence of

configure_simba <- function(driver_config,
                            action = "modify", call = caller_env()) {
  if (!is_macos()) {
    return(invisible())
  }

Thanks for the report!

Can replicate. We should be able to address soon. Stay tuned.

Thank you both for the reports. Do you have the ability to test development branches? If so can you test if this branch resolves the issue:

Thank you!
