I have a flask app which will run a scrappy spider. The app works fine in my developement machine however when I run it in container the close method of the spider is not executed.

Here is the code to the spider:

I am getting an error in console:

Error :=({ : could not find function ":="

I am using a fuzzyjoin (by David Robinson) and tidyverse packages only. The function is accepted with no syntax errors. On execution the error is thrown at me. What could be the reason?

I've been trying to do this several days ago.

I want to make a query that gets all the businesses that are registered in one city, after that for each Business I'd like to get all products in business and finally store it onto a new object and send it as a response to front end.

This is the code I'm using:

Dearest,

This is similar to one script I have been running for months on my platform.

I have some long text inside a column (called "description") and I want to wrap it (no more than 20 characters per line). In order to do this, I have a function which inserts a break line "\n" in the text whenever needed. I then use kableextra's "linebreak" function on that text to make sure the linebreak is properly understood (and it is).

The final result is then processed via latex to generate a pdf. The trouble is that the text inside the description column, although broken as I want, is no longer left aligned. I am sure I have not had this in the past (before updating R to 4.0.3 and reinstalling kableextra).

Anyone who knows how to fix this will have my gratitude!

Thanks

Sorry about the long post. As I mentioned in the title I have a flask web app that takes in a url and sends it to the scrapy spider. The spider then goes through the response and scrapes the src of all found images.

Spider code:

I creating a database application on AndroidStudio using Kotlin for a University project. I am trying to create the database using SQLite. Below is my DBHelper kt file that I created to start the database. When I call one of the functions to create the database, the application crashes. When I check the .db files from the database in SQL Cypher the tables do not appear. The errors aren't descriptive enough for me to find out how to fix it. Thank you for your help.

I have a data frame that looks like this:

I'm trying to take input from an interactive prompt via python's cmd library and pass the input to an autobahn websocket client to send up to a websocket server. The cmd loop and the autobahn websocket client loop are running in the same interpreter. I'm trying to use crochet to make that work. The websocket client connects to the server successfully but when I enter something at the cmd prompt to invoke sendMessage, I get the exception shown at the bottom of this post. Any guidance on where I may have messed up would be much appreciated. If there's a better approach to accomplish what I'm trying to do, I'm all ears.

These are the relevant imports and setup:

I'm running Scrapy from scripts, using Crochet library in order to block codes. Now I'm trying to dump logs into a file, but it starts to redirect logs to STDOUT for some reason. I doubt the Crochet library in my mind, but I don't have any clues so far.

1. How can I debug this kind of problems? Please share your debugging know-hows with me.
2. How can I fix it so that I dump logs into a file?
