QUESTION
I have separated the validation module in a async function. But it is not throwing destined error instead it is giving UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch().
Here is the validation function :
...ANSWER
Answered 2021-Jun-13 at 15:02pickupDateAndTimeValidation is a function that returns a promise (async functions return a promise). If the async function throws an exception, then that promise is rejected. If a promise is rejected, that rejection must be handled, else you will get that UnhandledPromiseRejection error.
So the problem in your code is that your promise-returning function is throwing an exception, but you aren't handling it. Look at how the validation function is called:

Looking at the postgres function array_position(anyarray, anyelement [, int])
My problem is similar, but I'm looking for the position of the first value in an array that is greater than an element. I'm running this on small arrays, but really large tables.
This works:
...ANSWER
Answered 2021-Jun-09 at 06:19I don't think that there is a more efficient solution than yours, except if you write a dedicated C function for that.
Storing large arrays is often a good recipe for bad performance.

I am trying to Compress and resize every image uploded. The image is not getting compressed, but its uploading in original dimensions. I want to reduce the size, by setting quality=60 and also set width to 100 to resize the image.

The code that procues this:
...ANSWER
Answered 2021-Jun-08 at 22:31There are multiple child nodes under Ride Requests. So when you use newRequestRef.child(rideRequestId).once(), your dataSnapShot contains the information for all of them.
When you access dataSnapShot.value['pickup'], there is no node Ride Requests/pickup, so it returns null. So when you then to dataSnapShot.value['pickup']['latitude'], you're calling ['latitude'] on null, which is what the error message says.
To solve this, you'll need to access the properties on the individual child nodes of Ride Requests. This use to be pretty tricky (see [here]), but now that this feature request has been implement, you should be able to loop over dataSnapshot.value.values.
So something like:

I have this array of multiple objects, and based on the quantity, I managed to multiply the objects with similar id based on the quantity to make a carousel of products for a picking app:
I can´t figure out how to do it, maybe run a for loop. I'm using reduce to flatten the array.
...ANSWER
Answered 2021-Jun-08 at 16:05As @Heretic Monkey suggested you can indeed use the second argument in the array.from method. As such with very minimal adjustment to your example you get the following code, what (I believe) does exactly what you want.
QUESTION
I am new to R programming and most of my experience thus far is with using highly structured rectangular data from a .csv or .xlsx. But now I've been handed about 30 spreadsheets of budget data that look like this:
And in order to work with them, I'd like to get them into a more friendly format (not exactly tidy b/c of the Q1 to Q4 could/should be a single variable -- but I can fix that later with pivot_longer), like this:
Searching SO, the closest problem/solution I found was this: R importing semi-unstructured data CSV, but that example contains a series of structured tables that do not require the modification mine does, plus, it is a text file converting to character vectors, and I have Excel workbooks with multiple worksheets (I only need 1 of the sheets).

QUESTION
I have an AWS Amazon Linux 2 box. I am using a python script (Python 3.7) to send an email using Sendgrid as the SMTP service. I can send the email using $ python3 send_email.py but, when I use crontab ($ crontab -e then * * * * * python3 ~/apps/send_email.py), the error in the log file /var/log/cron is (CRON) EXEC FAILED (/usr/sbin/sendmail): No such file or directory. The crontab is working as expected (I've tested other cron commands and they work fine), but the email part is what's not working.
Here's what I've tried to fix it:
- Run the command as a root crontab (ie
$ sudo crontab -e) - Run the the crontab as a user crontab (ie
$crontab -e)), but withsudo python3 ...in the crontab command. - Add the path directory at the top of the crontab file in case those directories couldn't be resolved
- Installed Postfix to install something in the
/usr/bin/sendmaildirectory but, since I don't need it to run the Sendgrid-powered email using$ python3 send_email.py, I'm not sure why I would need it through cron. I could be totally wrong on this, though. With Postfix installed, it resolves the(CRON) EXEC FAILED (/usr/sbin/sendmail): No such file or directoryerror in the cron log - the log entry in that case is(ec2-user) CMD (python3 ~/apps/send_email.py)- but I don't receive an email. Probably because Postfix isn't configured for the SMTP I'm using (Sendgrid). - (EDIT) I have configured Sendgrid to work with Postfix via the Sendgrid docs but it still won't send me an email although it looks like nothing is erroring out in the Postfix logs...
ANSWER
Answered 2021-Jun-05 at 20:28I was able to finally resolve this after much troubleshooting. Here's what worked.
- I kept the original setup the same: Sendgrid for SMTP using their python lib (no Postfix or smtplib), using user crontab (using
$ crontab -enot$ sudo crontab -e), and using Python 3.7. - Apparently the word 'email' in the python script name can cause interpreter issues so I renamed the file to remove the word 'email'. For example,
send_noti.pyinstead ofsend_email.py - I used absolute paths for every call to a file in the python script. I was reading, writing, and executing files in the user directory in my python script as well as sending an email. Those R,W,X commands started erroring out in cron but not when called from outside of cron for some reason, even after renaming the file. Using absolute paths for all references to files fixed that.
- I also used the absolute path for the python file in the crontab file. For example,
* * * * * python3 /home/ec2-user/apps/send_noti.pyinstead of* * * * * python3 ~/apps/send_noti.py - I removed the unnecessary items in the crontab file I had put in before such as redefining the PATH directory.
I hope this helps someone because this took me about 3 weeks to troubleshoot and figure out.
QUESTION
I am trying to make a Function, that automaticly updates the Post status to Completed if the status is wc-ishoej-afhentning, wc-roskilde-afhent, wc-koege-afhentning, wc-soeborg-afhent or wc-birkeroed-afhent. But it can only change the status, if a metakey(Delivery date) in postmeta is == the meta value of the Delivery date is == The current date.
This is an image of the values from every order in the database I believe the format is j F, Y

Answered 2021-Jun-05 at 10:07This is how it should be done. Go through the code carefully. I have added comments for you to understand what every function does.
