Selenium Invalid Argument when added driver.get() value from a function

Question

Update/Solution

I decided to rework the code a little. I ended up using pandas read_csv instead to open the urls.csv and iterated over the df columns with iterrows(). Everything is working now. Below is the updated code snippet.

df = pd.read_csv(urls, header=0, encoding="utf8", index_col=False)

for index, row in df.iterrows():
    report_type = row[0]
    report_name = row[1]
    file_name = row[2]
    download_report(report_type, report_name, file_name)

I am working on automation some report downloads using Selenium. I wrote the original python script that was too repetitive so I decided to combine thing into a function. This function navigates to a specific place in the system, generates a report by matching a name, downloads the report and moves/renames it.

def download_report(q_type, report_name, file):
    driver.get(q_type)
    driver.find_element_by_xpath("//select[@name='SavedQueriesDropDownList']/option[text()='%s']" % report_name).click()
    driver.implicitly_wait(3)
    driver.find_element_by_xpath("//input[@type='submit' and @value='Run Query']").click()
    driver.implicitly_wait(3)
    driver.find_element_by_id('exportsLinksDiv').click()
    driver.implicitly_wait(3)
    driver.find_element_by_id('ListToolbarRAWEXCELExportLink').click()
    time.sleep(5)
    filename = max([path + "\\" + f for f in os.listdir(path)], key=os.path.getctime)
    print(filename)
    os.rename(filename, out_path + file)

I have all of my data that the function needs in a csv file that includes three columns: q_type which it the starting URL path, report_name which tells the driver which report to select and file which is a file name that I want the downloaded file to be renamed as.

I am passing the needed value to the function with the following:

with open(urls, encoding="utf8") as csvfile:
      reader = csv.reader(csvfile, delimiter=',', quotechar='|')
      for row in reader:
          report_type = row[0]
          report_name = row[1]
          file_name = row[2]
          download_report(report_type, report_name, file_name)

When I run the script I get an error on the first line of the function driver.get(q_type):

Traceback (most recent call last):
  File "C:/nf4.py", line 52, in <module>
    download_report(report_type, report_name, file_name)
  File "C:/nf4.py", line 10, in download_report
    driver.get(q_type)
  File "C:\venv\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 333, in get
    self.execute(Command.GET, {'url': url})
  File "C:\venv\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 321, in execute
    self.error_handler.check_response(response)

    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.InvalidArgumentException: Message: invalid argument
  (Session info: chrome=76.0.3809.100)

For testing I printed out the value of q_type from the function and can confirm that it pulls the url from the csv file and it pulls it as a string. Really not sure where the error is coming from.

I am using the following driver setup:

# Setup Chrome Driver
chrome_path = r'C:\drivers\chromedriver.exe'
chrome_options = webdriver.ChromeOptions()
prefs = {'download.default_directory' : r'C:\data-in\raw'}
chrome_options.add_experimental_option('prefs', prefs)
driver = webdriver.Chrome(chrome_path, options=chrome_options)

Answer 1

I suspect that your q_type does not have a leading http:// (or https://) in front of the URL. That would cause the error message you are seeing. Can you verify if this is the case?
