Hi,

I really like this tabulizer and it's working very well. However, I recently tried to process a number of pdfs and am getting this error. Thought I'd pass it along.

Thanks ALL_2017_08_31.pdf

Did you find a solution? I have the same error. And seems like some pages in the pdf file causing this. Do you know which pages in the example you give having the error?

I have the same problem with this file: 452216668-Datos-18-03-20.pdf

Interestingly, the other files from the same website give no issues.

NEW FILE (errors): 453061401-Datos-23-03-20.pdf

OLD FILE (works): 451150373-Datos-10-03-20.pdf

The issue only appears in the NEW FILE when using lattice:

source_pdf = "453061401-Datos-23-03-20.pdf
extract_tables(source_pdf, method = "lattice") # error
extract_tables(source_pdf, method = "stream") # works

And it seems to be located in page 4:

source_pdf = "453061401-Datos-23-03-20.pdf
extract_tables(source_pdf, method = "lattice", pages = c(1:3)) # works
extract_tables(source_pdf, method = "lattice", pages = c(4)) # fails

Everything works fine with the OLD FILE.
