Hey @rotcivegaf thanks for raising this issue. Did you try it on Truffle v5.0.18? Would like to know what the earliest version is where this is broken for you, so that we can look at the changelog for the root cause.

Regardless, we'll look into this issue and see if we can't get it fixed in a jiffy.

[rotcivegaf]

This is the latest version that works

Truffle v5.0.13 (core: 5.0.13)
Solidity - 0.5.8 (solc-js)
Node v11.5.0
Web3.js v1.0.0-beta.37

Maybe the bug its in this release
Maybe in this Internal Improvement:
Reformat migrations and implement cleaner dry run behavior (#1905 by @eggplantzzz)

@rotcivegaf I actually get a different error when I try to follow the steps above with both [email protected] and [email protected].

Error: Error: ENOENT: no such file or directory, stat '/Users/tyler/projects/external/rcn-network/migrations'

Do you have any insight on this error?

[rotcivegaf]

You need create a migrations folder

[gnidan]

Huh I thought we stopped requiring a migrations directory. If not, maybe we should.

[rotcivegaf]

Yes, in actual version is required, if you want i can open an other issue

I am facing a similar error where I am unable to run migrations/tests on the latest version. The exact error I am getting is

Deploying 'MockOracle'
   ----------------------
Error: Error: Error:  *** Deployment Failed ***

"MockOracle" hit an invalid opcode while deploying. Try:
   * Verifying that your constructor params satisfy all assert conditions.
   * Verifying your constructor code doesn't access an array out of bounds.
   * Adding reason strings to your assert statements.

I am pretty sure that there is something wrong with the compilation or artifacts creation process because I am able to compile contracts with older truffle version (5.0.6) and then run tests/migrations with the latest (5.0.19). Compiling with the latest version and migrating with an older version of truffle gives the same error.

I am not sure on exactly which version it broke. I directly upgraded from 5.0.6 to 5.0.19.
