UI Error: Unable to Render Document

[dev-testing-v]

Hi, After assigning the sample pdfs through the commands:

aws s3 sync s3://ai2-s2-pawls-public/example-data ./skiff_files/apps/pawls/papers/ --no-sign-request

cd pawls/cli
python setup.py install

pawls preprocess pdfplumber skiff_files/apps/pawls/papers

pawls assign skiff_files/apps/pawls/papers development_user@example.com --all --name-file skiff_files/apps/pawls/papers/name_mapping.json

name_mapping.json:
{
"34f25a8704614163c4095b3ee2fc969b60de4698": "pdf1", 
"3febb2bed8865945e7fddc99efd791887bb7e14f": "pdf2",
"553c58a05e25f794d24e8db8c2b8fdb9603e6a29": "pdf3"
}

docker compose up

However, on accessing the UI, the document is not rendering. Is there another process I might've skipped?
