Reading pdf files on SAS Viya 3.5

[acordes]

I follow on this blog post https://blogs.sas.com/content/sgf/2023/11/08/extract-text-from-a-pdf-file-using-sas-viya/ 

but for me it's not working. @pstyliadis 

Running this program

%let path = /Projects/Extract text from PDFs and create tables/mypdfs;
 
%put &=path;


proc cas;
   file log;
   table.dropCaslib /
   caslib='ac_pdf' quiet = true;
 run;

proc cas;
   session mySession;

   table.addCaslib /
     caslib="ac_pdf"
     description="pdf files"
     dataSource={srctype="path"}
     path="&path" subdirs=true ;
run;


proc casutil;
	list files incaslib='ac_pdf'; 
quit;

proc casutil;
    load casdata=''                                                              /* To read in all files use an empty string. For a single file specify the file name */
         incaslib='ac_pdf'                                                       /* The location of the files to load */
         importoptions=(fileType="document" fileExtList = 'PDF' tikaConv=True)   /* Specify document import options   */
         casout='pdf_data' outcaslib='casuser' replace;                          /* Specify the output cas table info */
quit;

I get the following errors in the log:

When I upload my pdfs to a caslib via sftp then it works with the following code. 

Except that it throws out the following problem note, but I think it should work once it gets solved by the admin.
