Error messages

[rjaffe-exponent]

Hi, I`m getting the following errors when running pdf_text() on multiple pdf files:

PDF error: Can't get Fields array<0a> PDF error (2126): Unexpected MC Type: 7 PDF error: Couldn't find trailer dictionary PDF error: Couldn't read xref table Error in poppler_pdf_text(loadfile(pdf), opw, upw) : PDF parsing failure.

Could you please provide more details on the meaning of these errors? I`m wondering if using "pdf_ocr_text" would solve the problems, but it would take too much time to test in all my files (the errors do not specify the files generating the issues).

Here my session info:

Can you include an example pdf please?
