TypeError: Cannot call method 'get' of undefined
at C:\Users\denman\workspace-nodejs\ExpressNodeUpAndRunning\app.js:112:25
I am trying to find out the line number of the error...
is 112 the line number of the app.js file where the error occurred? Then what is 25?
The 3 components are sourceFilePath:lineNumber:columnNumber.
So the error occurs on line 112, at column 25.

I have a problem during the execution of my python script from crontab, which consists of an insert operation in the firestore database.
db.collection(u'ab').document(str(row["Name"])).collection(str(row["id"])).document(str(row2["id"])).set(self.packStructure(row2))
When I execute normally with python3 script.py command it works, but when I execute it from crontab it return the following error:
The above exception was the direct cause of the following exception:

I really don't understand what's the problem, because the connection at the database works every time the script is started in both ways.
Is there a fix for this kind of issue?
I found something that might be helpful. There is nice troubleshooting guide and there is a part there, which seems to be related:
If your command works by invoking a runtime like python some-command.py perform a few checks to determine that the runtime
version and environment is correct. Each language runtime has quirks
that can cause unexpected behavior under crontab.
For python you might find that your web app is using a virtual
environment you need to invoke in your crontab.
I haven't seen such error running Firestore API, but this seems to match to your issue.
I found the solution.
The problem occured because the timeout sleep() value was lower than expected, so the database connection function starts too early during boot phase of machine. Increasing this value to 45 or 60 seconds fixed the problem.
#time.sleep(10) # old version
time.sleep(60) # working version
fdb = firebaseConnection()
def firebaseConnection():
# firebase connection
cred = credentials.Certificate('/database/axatel.json')
firebase_admin.initialize_app(cred)
fdb = firestore.client()
if fdb:
return fdb
else:
print("Error")
sys.exit()

Please help on this its a been a blocker for me.
This is because I was hitting http://localhost:4569 which isn't a user interface. So its throwing error.But if I create tables using aws cli and do some operations it just works fine without any issue.

I was getting this error when using chromedriver v2.33 - when I updated to v2.36 the error went away (this was on the mac using the chromedriver_mac64.zip file downloaded from: https://sites.google.com/a/chromium.org/chromedriver/downloads)
Question: org.openqa.selenium.webdriverexception: unknown error: call function result missing 'value'. Please look into below steps to resolve such error.
Answer: Update browser version. Please follow below steps to get the latest version of browsers.
Go to: https://www.seleniumhq.org/download/
CTRL+F and search "Third Party Browser Drivers". All browsers are listed there.
Click on browser name/version -It redirects to the another page. (E.g.- http://chromedriver.storage.googleapis.com/index.html?path=2.36/)
Download appropriate driver for your operating system.
Place driver into one of folder from where you are calling that driver to your selenium webdriver scripts. It works without any error.
Thanks :) !!

It is likely that you have another server running on the port Ops is trying to start with (default 9000) that is returning data which is not JSON decodable. The solution is to either start MemSQL Ops on a different port, or kill the server running at that port.
We will fix this bug in an upcoming release of Ops! Thanks for pointing it out.

I can fix this using <form type="POST" accept-charset="utf-16">.
Normally, I catch errors in application code and log them or email them to myself, but this error never reached my application code which runs on TurboGears 1.5.
Any idea on how I can hook in to catch and log errors generated by CherryPy, and secondarily, give the user a better 404 page?
The method of error handling listed at _cperror.html#unanticipated-errors
doesn't work for this sort of error (but kicks in on e.g. static file missing)
