Trouble with conducting a simple transaction via Vanilla JS

Technical Issue Reporting
#1

My code used to work a couple of months ago. It used to be a simple transaction from wallet to another through a click of a button and then it just stopped working as I was dealing with something called ā€œbufferā€. Itā€™s been really annoying and very hard to find a solution to this even though Iā€™ve been looking for ages. Apparently, the reason why this is happening is because the bundle given by the Solana documentation itself does not contain all of the dependencies which is a big issue.

What am I supposed to do in this case? Would appreciate it if someone can help me figure this is outā€¦

#2

What is the error(s) you get? Can you give more info about your project (like package.json dependencies) and the transaction code.

#3

Do you have any other socials in order for me to contact you as itā€™d be easier? I use a bundle through my HTML page which is why I donā€™t have a package.json file, and the dependencies are there but fail to function for some reason.

I can connect my wallet but nothing else works especially when Iā€™m attempting to fetch the userā€™s balance or the latest blockhash for the transaction.

This is the error I receive: Error: 403 : {"jsonrpc":"2.0","error":{"code": 403, "message":"Access forbidden, contact your app developer or [email protected]."}

#4

This is the bundle I use which previously worked but stopped working recently around 2 weeks ago.

https://unpkg.com/@solana/web3.js@latest/lib/index.iife.js

#5

I donā€™t know how to fix this but I think itā€™s the bundle Iā€™m using, is there a browserified version of @solana/web3.js? All Iā€™m doing is fetching the userā€™s balance, logging it in the console, and prompting a SOL transaction.

#6

Check the version history for this package and try to find the previous version that you were using when it worked - it may have updated with a breaking change. You should be using a specific CDN version.

#7

Scratch thatā€¦ How would I be able to implement a simple SOL transaction from one wallet to another via Vanilla JS with the new update?

#8

I keep on getting a 403 error from the API, not sure why.

https://api.mainnet-beta.solana.com/ 403

#9

I was messing around and it works on devnet but not mainnet-betaā€¦ It has something to do with the API. Any help?

#10

that 403 error could be a forbidden error

An HTTP 403 response code means that a client is forbidden from accessing a valid URL.

meaning that it may require some authentication?

#11

Itā€™s a public API, I donā€™t get why itā€™d ask for authentication. Iā€™ve seen other code and they use the same functions. All I did was use getBalance which is nothing crazy. Itā€™s definitely the bundle Iā€™m using or something, honestly a newbie but it used to work in early November!

As I said, is there any way I can remake this?

#12

My goal is to connect to my website with a button which is simple, Iā€™ve aleady done that but I canā€™t access the Solana API through a bundle which is actually public to everyone. I retrieve the userā€™s address, balance, and then prompt a transaction using Vanilla JS. I donā€™t want to use wallet-adapter or whatever itā€™s called, would like to stick to Phantom to keep it simple. I just donā€™t know why my code isnā€™t working anymore and itā€™s probably because I need an updated version of @solana/web3.js that is within a bundle.

#13

did you check in network tab to see if there is more info for that 403 error?

#14

Commitment has been confirmed but not authorized to make the request? Would you like to check the code yourself? and do you have any other socials I can contact you through? (like Discord)

#15

I donā€™t know how to check the code

#16

You can check the Solana docs for current SDK usage. You can also ask these questions in the Solana Discord.
