TypeError: Cannot read properties of undefined (reading '_bn')

I trying to debug why I get the above error when running my nodejs express server in railway. The full error:

It has something to do wih the @solana/web3.js package and some fixes suggested here (https://solana.stackexchange.com/questions/4077/bigint-failed-to-load-bindings-pure-js-will-be-used-try-npm-run-rebuild-whe) did not work. project-id: 060de268-5246-4c9c-b27e-dfaaf4e8fecc Everything is running fine locally.

forgive me for asking, but you have ran npm run rebuild right?

_daniel.sol | NFTs For Less•7mo ago

I have, yes.

(base) ➜  nftsforless-shyft git:(main) railway run npm rebuild
rebuilt dependencies successfully

(base) ➜  nftsforless-shyft git:(main) railway run npm rebuild
rebuilt dependencies successfully

I have also ran yarn cache clean

(base) ➜  nftsforless-shyft git:(main) railway run yarn cache clean
yarn cache v1.22.19
success Cleared cache.

(base) ➜  nftsforless-shyft git:(main) railway run yarn cache clean

still no change

Brody•7mo ago

you've totally removed node_modules as well?

_daniel.sol | NFTs For Less•7mo ago

yes

Brody•7mo ago

I noticed that you are using railway run, are you aware that only runs the given command locally?

_daniel.sol | NFTs For Less•7mo ago

no 🙂 I was under the impression that railway run, runs the command in the deployment environment

Brody•7mo ago

for this you wouldn't need railway run, just run the commands locally and push the changes

_daniel.sol | NFTs For Less•7mo ago

:rip: there are no changes to my repo if I run any of the mentioned 3 cmds

Brody•7mo ago

nope, there's no way to do that, and for this there's no need to do that, check out the --help printout for more information

_daniel.sol | NFTs For Less•7mo ago

so I have nothing to push

Brody•7mo ago

make sure you delete all the would be effected files before running those commands

_daniel.sol | NFTs For Less•7mo ago

I'm not sure I understand. I see a lot of "cached" when trying to railway up is there a command to make railway build fresh?

Brody•7mo ago

are you building with nixpacks?

_daniel.sol | NFTs For Less•7mo ago

yes

Brody•7mo ago

can't hurt to try, set a service variable NIXPACKS_NO_CACHE to 1

_daniel.sol | NFTs For Less•7mo ago

_daniel.sol | NFTs For Less•7mo ago

I have a feeling I'm not doing it right this is my railway.toml file

Brody•7mo ago

a service variable https://docs.railway.app/guides/variables#service-variables

_daniel.sol | NFTs For Less•7mo ago

gotcha nope, no change build seem to be fresh

Brody•7mo ago

didnt think this was a cache issue, what node version are you using locally, and what node version is railway building your app with

_daniel.sol | NFTs For Less•7mo ago

locally:

(base) ➜  nftsforless-shyft git:(main) ✗ node --version
v18.2.0

(base) ➜  nftsforless-shyft git:(main) ✗ node --version
v18.2.0

_daniel.sol | NFTs For Less•7mo ago

and from what I can tell railway is using 18 also?

Brody•7mo ago

im out of ideas, have you tried googling for the error? TypeError: Cannot read properties of undefined (reading '_bn') found this, i dont know your project so i dont know if its applicable though https://stackoverflow.com/questions/70235249/solana-candy-machine-typeerror-cannot-read-properties-of-undefined-reading-b

_daniel.sol | NFTs For Less•7mo ago

yeah, I was reading the exact thing, let me try a thing or 2 thank you for your help 🙂 I was missing an env var ...

Brody•7mo ago

makes sense given you might not have known about the service variables

_daniel.sol | NFTs For Less•7mo ago

no, I had all my vars in place, (got confused about the term - "service variables") but with one update, locally I introduced a new env var that I forgot to add in in railway thanks again for help it literraly bugged me for half a day :rip:

Brody•7mo ago

they're called service variables because it's a service and those are the services variables

_daniel.sol | NFTs For Less•7mo ago

now I know :respect:

Brody•7mo ago

glad its working!

_daniel.sol | NFTs For Less•7mo ago

once again, thank you for taking the time to help me

Brody•7mo ago

no problem! 🙂

Nereos•6mo ago

hey @_danielpavel, I am having a similar issue, what var exactly you forgot? the no cache one?

_daniel.sol | NFTs For Less•6mo ago

Well, I’m not sure how my particular case helps you. You have to check your code and see which one you’ve missed and used assuming it’s holds a value comming from your env but it’s actually undefined ‘cuz you have not set it
