Hello everyone.

I am developing an API using truffle-hdwallet-provider. The fact is that when I make calls to the API, most of the times it works, buteven if ti works, is very common for me to get error and the times it comes out, sometimes it works and sometimes it does not.

did anyone solve this issue?

hubiierik commented 6 years ago

Not a solution, but a tip: XMLHttpRequest has a weakness in it's implementation that it strips off error information when ready state is set. For whoever is inclined it is possible to see that information if the app is run in a debugger and breakpoint put inside XMLHttpRequest._onHttpRequestError(). The error parameter of that function should give a hint of what is going on.

Any updates on this?

theone3nu commented 5 years ago

I am also facing this issue especially if the smart contract is returning array of uints of length more than 1000. Some times it works some times it doesnt works. Any update on this issue.
