Data Table Issue

[significantis]

Description

Hello, I am successfully using the SSE-R-PLUGIN in Qlik Sense. However, I reckon there might be a glitch when passing some Qlik data to R and back in a data table.

My goal is very simple. I have a Variable, say Var1, with values 1 to 10. I put this variable in the first column of my data table. Then I select the second row and simply pass Var1 to R and back (identity). I expect a second column, say VarR, to be a copy of Var1, but Qlik shows an error. Saving the data on the server via R then shows that some data was not completely passed from Qlik.

Steps to Reproduce

1. Create dimension Var1 = 1, 2, 3, ..., 10.
2. Pass Var1 into a data table as dimension.
   
3. Open a second column VarR and add the following code: =R.ScriptEvalEx('N', 'q$v1', Var1 as v1) -> Qlik shows an error.
4. Change the code of VarR as follows: =R.ScriptEvalEx('N', '1:10', Var1 as v1) -> Works and shows a copy of Var1.
5. Change the code of VarR as follows: =R.ScriptEvalEx('N', 'saveRDS(q$v1, "test_data.rds"); 1:10', Var1 as v1) -> Gives a weird output for VarR with all 1s. In addition, the stored data in the backend is NULL.
   
   

Expected behavior

Qlik sends all data to R and back. A second column VarR appears with the same values as Var1.

Actual behavior

An error in Qlik. No data transmitted to R.
