Unable to Understand the Respective NFT Challenges

[avalsonigara15]

I am not able to understand what the challenges are and what is to be done. I read the #2018 issue , I understood where to locate the challenges but what exactly is to be done is still unclear.
I only found a bunch of functions but don't know what is to be done with those functions.
I am unsure with what to expect with those functions.
Please Help

Where to find the Instructions to solve the Challenges?

[EngrPips]

Alright, Thanks

[farman1094]

@EngrPips have you give a try to add a challenge it also showing me unusual fees

[EngrPips]

Hello @farman1094, You need to check that you haven't solved the challenge already with that same address you are using now as that will make it so your transaction will always fail. and secondly, what is the value you provided for the location parameter?

[EngrPips]

This is the contract address : 0x4A62A8901e6113dEF0AEeEC77E531779cd40da73

Hello @avalsonigara15, You are meant to call the solveChallenge function on the write tab of the contract page on etherscan but to call the solveChallenge function, you need to provide the index of the s_booleanArray, which is currently set to true. You might ask how you are supposed to know the index of the s_booleanArray that is set to true, so what you should do is check the last successful transaction call to the contract and decode the input of the transaction you will see the index of the s_booleanArray that the person set to true. If you have gotten that index, then you choose any index within the length -1 of the array and set it as the new index in s_booleanArray, which will be set to true.

As of this moment, of you call the solveChallenge with the details in the image below, the transaction should be successful

This worked the transaction went through but my question is how will I or anyone will be able to figure out what is to be done.
It is difficult to find any instructions regarding the challenge. How can I proceed further @EngrPips ?

[EngrPips]

Honestly, If you are unable to figure out the challenge it is a sign that you haven't understood properly everything that you have been taught so far and you should maybe redo the section.

please @EngrPips , What did you mean by "same address you are using now as that will make it so your transaction will always fail" cause i am facing it too.

[callgh0st]

Hello @EngrPips , Clarify if i'm wrong. I have to use diff wallet address to solve the challenge, right? I just did now and i stopped getting the "transaction might fail".

Hello @EngrPips ,
I'm having an issue with the "write". Once i input my twitter username, it pops out my metamask default interface.

Hello @EngrPips , I'm having an issue with the "write". Once i input my twitter username, it pops out my metamask default interface.

it seems the issue is from metamask.

[EngrPips]

Hello @callgh0st, when you click on write it is supposed to pop out your metamask so as to have you sign the transaction you want to make.

[callgh0st]

Hello @EngrPips , I'm already signed in. It seems the issue is with my metamask.

I disabled the extension then enabled it and it works. I was able to solve the challenge.

Thanks for your assistance.

[EngrPips]

Awesome, I am glad you figured it out. Keep crushing it.

[callgh0st]

Alright 👍 Thanks. Let me take a break then check it.

[EngrPips]

Yeah, Please always take breaks. They are very important.

Hello @EngrPips ,
Hope you're doing well!
I'm having an issue with lesson4. I already got the price but once i try to write the priceguess and username, i got this:
We were not able to estimate gas. There might be an error in the contract and this transaction may fail.

I'm using different wallet address. I deployed the PriceCv3 using injector provider(metamask), deployed, got the price(6294100000000). The price is tooooo high.
