Why does FireFox has the shittiest dev tools?
Working on my website and it kept throwing "TypeError: Failed to fetch"
with no other info

Opened Chrome and that thing gave me the entire error without even modifying my logs code, and now I can peacefully solve the problem -.-

Dear JavaScript,

"TypeError: Object(...)(...) is undefined" is not a helpful error message.

Sincerely,

Me

TypeError: connect () takes at least 4 arguments (4 given) Oh ok that makes sense...

Weird!! Just from the dentist's and all through the procedure all I could think of is why my python code is throwing a typeError. I mean I should have been sharting myself.

Hiii devRanters, I have a TypeScript question for you...
How do I dynamically import classes?

I have a class like this:
export default class Foo implements Bar {
...
....public getName(): string {
........return this.name;
....}
}

and then I have another file with this:
import(`./class-cmd/${file}`).then((command) => {
....winston.debug(command);
....winston.debug(command.getName());
});

the first command spits out something like this:
debug: default=class Foo {
....constructor() {
........this.name = "foo";
....}
....getName() {
........return this.name;
....}
}

and I would expect that the second command will work, however it throws this:
UnhandledPromiseRejectionWarning: TypeError: command.getName is not a function

Any idea what I might be doing wrong?

hey node what type is this?

> typeof []
'object'

but then

> Object.defineProperties.call([])
Uncaught TypeError: Object.defineProperties called on non-object

so is [] an object or not?

Python be like:
TypeError: 'callable_iterator' object is not callable
and also:
TypeError 'callable_iterator' object is not subscriptable

Why the fuck did you name it "callable iterator" if you can't call it, or iterate it.

TypeError: unsupported operand type(s) for +: 'SpiritualConcept' and 'int'

ANYONE USING MONGOOSE HERE?!!

TypeError: User is not a function.

That User is a Schema. I've been searching for so long now and I can't seem to find a way to make this work. Sorry for being desperate that I had to ask on devRant.

Oops! Something went wrong! :(

Did someone move fast and break things again?

TypeError: can't pickle _thread.lock objects

someone please guide me .....

Colleague: Can you help me with something when you're not busy?
Me: TypeError: cannot concatenate 'not' and 'busy' as <status>!

I guess it doesn't help that I do my work in a non-dev environment...

On the plus side, it's very hard to be bored as a developer :)

*sigh*

Python:
TypeError: unsupported operand type(s) for %: 'tuple' and 'dict'

Ugh there's a comma somewhere. I kinda appreciate how easy it is to make a tuple, but at the same time I don't. If there's no value after a comma with only one value behind it, could the linter at least mark it as a warning?

Hey Devrant fam!, well i'm basically trying to see if i can change up this A* algo we need to implement for an assessment, and from what i know basically most people have copy and pasted it, but not me!, so there is this one called Easy A* (star) Pathfinding By Nicholas Swift and my goal is such that i would like to make it input friendly!, here is the code in my main function

def main():
start1,start2 = input('Enter co-ordinates').split(',')
end1,end2 = input('Enter co-ordinates').split(',')

drive_mount()
open_map()

# test1 = (start1, start2)
# test2 = (end1, end2)

start = (start1, start2)
end = (end1, end2)

print(f'start co-ordinates:{start} \n end co-ordinates:{end}')

our_path = astar(our_maze, start, end)
print(f'starting co-ordinates:{start} \n ending co-ordinates:{end} \n Your shortest-path:{our_path}')

if __name__ == '__main__':
main()

however i am then greeted by this error, on line 62 specifically it says "TypeError: must be str, not int" and my original thought was to put str() around all of them, but that does not seem to work :-) any advice? thank you!

Python working non-deterministic on VSCode? That just happened ... somehow, wtf??
Getting a list from a method and comparing its last element with an int value. Always worked before like a charm, didn't change a thing. All of a sudden TypeError, cannot run anymore? Restart VSCode, run again, still not running ... ?? Retry and print the element, in case I've surprisingly actually been an idiot all along ... nope, value looks in print as expected. Continue execution, suddenly condition works again. WTF just happened??? Caching, python extension bug, anything like that to blame?

I am trying to extract data from the PubSub subscription and finally, once the data is extracted I want to do some transformation. Currently, it's in bytes format. I have tried multiple ways to extract the data in JSON format using custom schema it fails with an error

TypeError: __main__.MySchema() argument after ** must be a mapping, not str [while running 'Map to MySchema']

**readPubSub.py**

import apache_beam as beam
from apache_beam.options.pipeline_options import PipelineOptions
import json
import typing

class MySchema(typing.NamedTuple):
user_id:str
event_ts:str

event_id:str
ifa:str
ifv:str

device_model:str
user_name:str
fb_connect:bool
is_active_event:bool
event_payload:str

TOPIC_PATH = "projects/nectar-259905/topics/events"

def run(pubsub_topic):
options = PipelineOptions(
streaming=True
)
runner = 'DirectRunner'

print("I reached before pipeline")

with beam.Pipeline(runner, options=options) as pipeline:
message=(
pipeline
| "Read from Pub/Sub topic" >> beam.io.ReadFromPubSub(subscription='projects/triple-nectar-259905/subscriptions/bq_subscribe')#.with_output_types(bytes)
| 'UTF-8 bytes to string' >> beam.Map(lambda msg: msg.decode('utf-8'))
| 'Map to MySchema' >> beam.Map(lambda msg: MySchema(**msg)).with_output_types(MySchema)
| "Writing to console" >> beam.Map(print))

print("I reached after pipeline")
result = message.run()
result.wait_until_finish()

run(TOPIC_PATH)

If I use it directly below

message=(
pipeline
| "Read from Pub/Sub topic" >> beam.io.ReadFromPubSub(subscription='projects/triple-nectar-259905/subscriptions/bq_subscribe')#.with_output_types(bytes)
| 'UTF-8 bytes to string' >> beam.Map(lambda msg: msg.decode('utf-8'))
| "Writing to console" >> beam.Map(print))

I get output as

Please let me know if I m doing something wrong while parsing the data to JSON. Also, I am looking for examples to do data masking and run some SQL within Apache Beam
