ValueError: Coordinate 'right' is less than 'left'

[atgreen]

Given this code:

import openparse

basic_doc_path = "mydoc.pdf"
parser = openparse.DocumentParser(
    table_args={
        "parsing_algorithm": "unitable",
        "min_table_confidence": 0.8,
    }
)

parsed_basic_doc = parser.parse(basic_doc_path)

for node in parsed_basic_doc.nodes:
    print(node.json())

I'm getting the following error:

If it helps, my input document is this one: https://www.rbc.com/investor-relations/_assets-custom/pdf/ar_2023_e.pdf

Thanks for this great library.

I'm also getting ValueError: Coordinate 'right' is less than 'left' with this PDF
and almost the same code:

import openparse

basic_doc_path = "sample.pdf"
parser = openparse.DocumentParser(
    table_args={
        "parsing_algorithm": "unitable",
        "min_table_confidence": 0.8
    },
)

parsed_doc = parser.parse(basic_doc_path)
