Cant load app into browser

See original GitHub issue

I’m tried to solve the following problem using pdfkit (Flask). when I add wkhtmltopdf configuration to my app then my app can’t load into the browser even the index page cant load into the browser. but when I remove wkhtmltopdf configuration from my app then my all routes work fine only the HTML to pdf route gives me the following error.

OSError: No wkhtmltopdf executable found: "b''"
If this file exists please check that this process can read it. Otherwise please install wkhtmltopdf - https://github.com/JazzCore/python-pdfkit/wiki/Installing-wkhtmltopdf

Configuration:

config = pdfkit.configuration(wkhtmltopdf='C:\\Program Files\\wkhtmltopdf\\bin\\wkhtmltopdf.exe')
pdfkit.from_url('http://127.0.0.1:5000/leave_worker_pdf', 'output.pdf', configuration=config)

route.py code:

@app.route('/leave_worker_pdf', methods=['POST'])
def leave_worker_pdf():
    leave_worker = LeaveWorker.query.all()
    html = render_template("leave_worker_pdf.html", leave_worker=leave_worker)
    pdf = pdfkit.from_string(html, False)
    response = make_response(pdf)
    response.headers["Content-Type"] = "application/pdf"
    response.headers["Content-Disposition"] = "inline; filename=output.pdf"
    return response

You should provide configuration arg for any API since its not stored anywhere.

Try changing to

def leave_worker_pdf():
    leave_worker = LeaveWorker.query.all()
    config = pdfkit.configuration(wkhtmltopdf='C:\\Program Files\\wkhtmltopdf\\bin\\wkhtmltopdf.exe')
    html = render_template("leave_worker_pdf.html", leave_worker=leave_worker)
    pdf = pdfkit.from_string(html, False, configuration=config)
