Using PDF2Image in Code Repository on Palantir Foundry - palantir-foundry

Question

I am trying to use the library pdf2image in a Code Repository on Palantir Foundry and getting the error
pdf2image.exceptions.PDFInfoNotInstalledError: Unable to get page count. Is poppler installed and in PATH?
when using the function convert_from_bytes.
Does anyone know how to reference the poppler path and get rid of this error?
Thanks!
Here is the code:
def extract_pdf_text(input_bytes, language='eng', dpi=200):
pages = convert_from_bytes(input_bytes, dpi)
pdf_pages = ''
for page_index, page in enumerate(pages):
pdf_page = pytesseract.image_to_string(page, lang=language)
pdf_pages = pdf_pages + pdf_page
return pdf_pages
And the meta.yaml for reference:

# update the 'requirements.run' section in this file

Answer 1

I found the problem when inspecting the CI-Checks. They failed before poppler was pulled. After I cleaned up meta.yaml and the checks succeded everything seems to work fine.
