QUESTION
I am currently implementing Adyen Web Drop-in integration but ran into a problem testing it on staging.
From the Adyen developer console I can see the API request and response for the session endpoint which returns the sessionData payload as expected.
We then pass sessionData into a page which renders the form correctly.
...ANSWER
Answered 2022-Mar-21 at 20:17After a bit of back and forward with Matthew here's the solution.
We have seen this error happening before on the test environment, and the best way to resolve is to use another API user. Would it be possible to create a new API user as described here, or use another of the existing ones? Using the API Key and Client Key from the new user should resolve the issue.
QUESTION
I'm trying to implement an end-to-end proof-of-concept to exercise Adyen's Web Drop-In. Roughly, this involves three steps, as shown at that URL, but repeated here for convenience:
- Create a payment session
- Set up Drop-in
- Get the payment outcome
Step 1 is done on the server, and the session data is returned to the browser. That part's working fine. Step 2 has to be done in the browser because it requires the DOM, and this is (naturally) where the CORS problems arise. Here's the problematic code:
...ANSWER
Answered 2022-Mar-18 at 09:10What is most likely to happen is that you have not added your application's URL into the "allowed origins" list of your credentials.
You can do this by going to the Developers -> API Credentials page of the customer area, selecting the right credential there and adding a new "Allowed Origin".
That should solve your CORS issues

QUESTION
I am trying to append data from the list json_response
containing Twitter data to a CSV file using the function append_to_csv
.
I understand the structure of the json_response
. It contains data on users who follow two politicians; 5 and 13 users respectively. 1) author_id
, created_at
, tweet_id
and text
is in data
. 2) description
/bio
is in ['includes']['users']
. 3) url
/image_url
is in ['includes']['media']
. However my nested loop does not append any data to sample_data.csv? and it throws no error. Does it have something to do with my identation?
ANSWER
Answered 2022-Jan-10 at 21:24Looks like the else branch of if 'description' in dic:
is never executed. If your code is indented correctly, then also the csvWriter.writerow
part is never executed because of this.
That yields that no contents are written to your file.
A comment on code style:
- use
with open(file) as file_variable:
instead of manually using open and close. That can save you some trouble, e.g. the trouble you would get when the else branch would indeed be executed and the file would be closed multiple times :)
QUESTION
I am trying to extract an element from a list and append it to a CSV file.
json_response
is a list containing data on Twitter users who follow two politicians. For the first politician there are 5 tweets/users and for the second politician 13 tweets/users as can be seen from the structure of json_response
. I want to extract the description
for each user which is contained in ['includes']['users']
. However, my function only extracts the last description
5/5 user and 13/13 user for each politician.
My knowledge regarding JSON-like objects is limited.
...ANSWER
Answered 2022-Jan-10 at 16:56I believe the problem relies in the append_to_csv
function because of a wrong indentation.

QUESTION
I am creating a FMP4 with 2 tracks (one for video and one for audio). I trying to find out how many video samples should I include in the mdat and how many audio as well.
So my FMP4 has the following structure:
...ANSWER
Answered 2021-Nov-12 at 15:30From several empirical testing using ffmpeg, it appears that it likes to group 0.5s of video frames followed by 0.5s of audio frames and that appears to work really well.
QUESTION
For a given AV file, I need to be able to seek to a particular video frame number in the file. Because of how decoding works, I am seeking to the nearest I-Frame before the required frame (which may or may not be the requested frame) and then decoding the frames in the GOP until I get to where I need to be. As such, I need to know my current position after seeking.
Having found some posts of a similar nature on SO, I've gone away and collected a few interesting samples to see if I can get a formula to work across many different files, but I'm having a hard time. What works or 1 file may not work for another:
File #1 (Podbox)
Requested to seek to fame #1500. First video frame reports:
...ANSWER
Answered 2021-Sep-27 at 03:52Most formats and ffmpeg don't keep track of absolute frame indexes. Timestamp is the benchmark.
There are two workarounds:
#1 Remux to MP4 or MOV and then seek. The demuxer will print a trace level log.
QUESTION
I'm using the FFMPEG Api in Rust to get RGB images from video files.
While some videos work correct and I get the frames back as expected, some work not. Or at least the result is not the way I expected it to be.
The code I use in Rust:
...ANSWER
Answered 2021-Sep-13 at 10:22Thanks to the suggestions of @SuRGeoNix and @Jmb I played around with the linesize and width of the input.
After a bit I learned that ffmpeg requires 32bit aligned data to perform optimally. So I adjusted the scaler to scale to a 32bit aligned width and the output is fine now.
QUESTION
Facing issue with @Detail when passing value in function through string 'ABC' the getting correct output but when passing via variable then getting incorrect output. What i am doing wrong.
...ANSWER
Answered 2021-Sep-09 at 16:54OK, so that query I had you run is showing that the character between 12:15:0 11/13/2019
is a TAB (ascii character 9), not a space (ascii character 32)
This is why you get the output you do; you should perhaps consider to replace tabs with spaces before you split, or upgrade your split function so you can pass multiple chars to it for splitting (I assume that's what the ' '
parameter is for)
When you copied your value out of SSMS results grid it swapped the tabs for spaces already (SSMS converted the tabs to spaces), so when you ran it, it "looked the right output" when using the hardcoded value that contained only spaces..
..but the data in the DB table definitely has tabs! Always be careful copying stuff out of SSMS results grid; it drops characters, changes characters and cuts longer data off at the end, so it cannot be guaranteed to be an accurate reflection of what is in the table.
QUESTION
I'm trying to make it so that when you run the message collector and when it awaits for a word such as "Lincoln," It changes it to uppercase. I tried to do it at the beginning of the code
(let msg = message.content.toUpperCase();
), but it still doesn't receive it as uppercase, (so lincoln
isn't accepted but Lincoln
is) here is the full code:
ANSWER
Answered 2021-Aug-24 at 21:35If you would like to make your code accept inputs, case-insensitive, you can make the string upper or lower case. Note that toUpperCase()
and toLowerCase()
will make all characters upper/lower case.
