If i leave GUI i can keep working...

Hi @CodeFuriate, it would be helpful for reproduction if we could see the dapp you're working with. Is there a repo you mind sharing?

[theophoric]

I am having this issue as well.

[CodeWarriorr]

@DiscRiskandBisque Yes, https://github.com/GeonNetwork/geon-ethereum

[davidmurdoch]

Thanks @CodeFuriate! We're looking into it and working on a fix now!

Hm, I don't seem to be able to reproduce this issue. It's possible later versions of the decoder fixed this, maybe? (I've been using the development versions.) I guess I may have to retry with the released versions to be sure, though I'm skeptical there's been any relevant change. But for now I'm fairly stumped, because I haven't been able to reproduce this; I haven't gotten any errors of this form either upon inspecting contracts in this project with Ganache, or just checking out the storage allocations from the debugger's debug info. Allocation seems to be working fine here, so I'm not sure how I can isolate the problem at the moment, unfortunately. But like I said I'll try again shortly.

[haltman-at]

Oops, seems I made a mistake above -- I was using the application bundle, meaning I was using the released version after all. Meaning, I can't reproduce this, sorry. We'll have to figure out some other approach here, I suppose...

[davidmurdoch]

This should now be fixed in our latest beta: https://github.com/trufflesuite/ganache/releases/tag/v2.0.1-beta.0 Let me know if you have any issues or if the fix doesn't work for you.

[CodeWarriorr]

@davidmurdoch sadly its not https://github.com/trufflesuite/ganache/issues/1256
It starts with "truffle projects" configuration and makes Transaction details and Contracts details crash.
I have full list of deployed contracts but viewing any of them causes a crash (probably loading transactions part crashes)

[amorriscode]

Still appears to happen to me on 2.0.1.631.

[haltman-at]

So, we're currently looking into the problem, but I wanted to suggest a workaround until such time as we have a fix. Would you mind trying this and letting us know if it works? Try recompling your Truffle project with truffle compile --all, or, if necessary, recompiling and redeploying the whole thing with truffle migrate --compile-all --reset.

See if that fixes the problem for now; let us know if it works. Meanwhile, we are, as I said, looking into a more proper fix. Thank you!

[haltman-at]

OK @davidmurdoch, you are presumably already aware of this, but writing this down here where you can find it again more easily: I just merged this Truffle PR, which causes the decoder to throw a special class of error when this error condition comes up, so that you can catch it rather than crashing. Obviously that's not a proper fix, but a proper fix is still being worked on; in the meantime, once Truffle 5.0.14 (or rather, truffle-decoder version 3.0.1) is released, if you upgrade your decoder version you'll be able to catch the error.

Note that Truffle 5.0.13 (or rather, truffle-decoder version 3.0.0) included a breaking change to the decoder, in that init is now async, so you'll have to change that if you haven't already. But obviously that's pretty minor.

This issue should be fixed in the latest beta! https://github.com/trufflesuite/ganache/releases/tag/v2.0.2-beta.0
