Hi,

I am trying to pull the Salesforce data using the salesforce plugin available in Logstash. Below is my configuration.

ELK Version : 7.4

```
input {
  salesforce {
   use_test_sandbox => true
    client_id => 'xxx'
    client_secret => 'xxx'
    username => 'xxx'
    password => 'xxx'
    security_token => 'xxx'
    sfdc_object_name => 'xxx'
  }
}
output {
 elasticsearch {
    hosts => ["https://xxx:443"] //443 because using Managed ElasticSearch
    index => "salesforcelog-%{+YYYY.MM}"
       user => "xxx"
        password => "xxx"
        ilm_enabled => false //using this for Managed ES 
  }
    stdout { codec => rubydebug }
}

```

I end up getting the below error.

`[ERROR] 2020-10-27 09:16:09.119 [[main]-pipeline-manager] javapipeline - Pipeline aborted due to error {:pipeline_id=>"main", :exception=>java.lang.ClassCastException: org.jruby.ext.set.RubySet cannot be cast to org.jruby.RubyFixnum`

Please help me resolve this !! Thank you

Is there a stack trace for that error message?

That is strange. The salesforce client is initializing, and during initialization it does a [describe](https://github.com/logstash-plugins/logstash-input-salesforce/blob/4f34d24c5ed6b9ddb1f0ec0730710ddea9dd136d/lib/logstash/inputs/salesforce.rb#L90) of @sfdc\_object\_name. I believe that involves doing a GET on it. Down inside the faraday HTTP client it appears to blow up at [this](https://github.com/lostisland/faraday_middleware/blob/a46ae1a7a7c21b7c5be925f9eb46b31e89c4e094/lib/faraday_middleware/response/follow_redirects.rb#L71) line of code.

Looking at the error message

```auto
:exception=>java.lang.ClassCastException: org.jruby.ext.set.RubySet cannot be cast to org.jruby.RubyFixnum, 
:backtrace=>["org.jruby.runtime.invokedynamic.MathLinker.fixnum_op_lshift(MathLinker.java:297)",
"java.lang.invoke.MethodHandle.invokeWithArguments(MethodHandle.java:627)", 
"org.jruby.runtime.invokedynamic.MathLinker.fixnumOperator(MathLinker.java:171)",

```

fixnum\_op\_lshift is what gets the exception. I cannot conceive how

```
  @convert_to_get = Set.new [303]
  @convert_to_get << 301 << 302 unless standards_compliant?

```

could throw that exception. @convert\_to\_get is a Set, why would it try to cast it to a Fixnum when adding a Fixnum (301) to the set?

This is in the initialize function, so I would expect it to always go through this code. It is not processing a redirect at this point, so it is not handling a response from Salesforce, it is initializing so that it can do so in the future.

I am baffled. Sorry I cannot be more help.
