RStudio, issue with pdflatex converting .tex to pdf file

Question

I am trying to run a conversion using pdflatex of output.tex to a pdf and it gives me this error message: The output.tex was created using knitr using data_exploration_report.Rnw file

knit(report_file, output = file_name)

"Sorry, but C:\\Users\\app1ebb\\DOCUME~1\\R\\MiKTeX\\miktex\\bin\\x64\\pdflatex.exe did not succeed."

And then the warnings:

Warning message:
running command 'C:/Users/app1ebb/Documents/R/MiKTeX/miktex/bin/x64/pdflatex.exe C:/Users/app1ebb/Documents/AA/RToolkit/exploration-kit/temp/output.tex' had status 1 

I looked at the log and I can not make sense out of it:

Im running Windows 10 and I can see that my MikTeX is on my path already . I am running R version 3.4.2 and RStudio 1.1.383

And here is my path:
