[nicos99]

this fix seems to work

Thanks @nicos99 for opening the issue and sharing your findings.
Could you open an MR for this fix?

Also I encourage you to check with web3.js version 4. As version 1 will be deprecated later.
So, could you, please, check with version 4 and share your findings?

[nicos99]

ok, I'll check with version 4 and open a PR (probably this weekend)

[nicos99]

Then @Muhammad-Altabba it turns out that with version 4.2.2 (from 'https://cdn.jsdelivr.net') there is no problem!
The error object caught is generic (.message: "Internal JSON-RPC error.") but we have access to the data sub objet that gives details I was looking for (.data.message: "err: insufficient funds for gas * price + value: address 0x<HHH...> have <AAA...> want <BBB...> (supplied gas <GGG...>)", the exact message differs slightly between the networks/provider but the structure is identical).

[Muhammad-Altabba]

Congratulations @nicos99 that version 4 worked with your case.
It is hard to fulfill the different specifications of every network (in your case Polygon). But we try our best 😄 .

Since the issue is not present in web3 v4. I will suggest to close this issue. And for those who use web3 v1, we encourage them to upgrade. Does this work for your case?

[nicos99]

Thank you @Muhammad-Altabba. I've partialy switched to web3 v4 for my dApp and it will require more validation so for now I'm still on 1.x with my fix. I think this protects against other bugs of the same kind (because we are in a scope not protetced by a try/catch so we have to check carefully each fields access) so I'm going to open a PR soon. I suggest you can tag this bug "1.x" and close it if the PR is not merged quikly.

[Muhammad-Altabba]

Thanks @nicos99 for your understanding, and many thanks for reporting this and trying to fix it on 1.x.

And for those who encounter this issue they can upgrade to version 4.x.
