Before the update

Before the update of the code of my c++ smart contract, this uses to work absolutely fine. Data storing on the table and actions execution were done successfully.

After the update

After I updated the code - adding some functions and not touching the tables - it started showing this error:

Error 3050003: eosio_assert_message assertion failure
Error Details:
assertion failure with message: read
pending console output:

What I tried

  1. I tried to change the table names and execute the update code again (didn't work);
  2. I tried to revert the contract to the exactly previous code (didn't work);

  3. I tried to add $NODEOSBINDIR/nodeos --verbose-http-errors true to the script that starts the node (nothing more is shoed in the error output);

  4. I tried to access the table after changing its name, and I could do it (but of course is empty).

What I am looking for

  1. If anyone experienced the same issue please help to figure out more details about this eosio_asser_message;
  2. A clear explanation on how to update smart contracts with tables and what happens in different use cases;
  3. If I made some mistakes in the configuration of the flag --verbose-http-errors true.
  • Try to start nodeos with --verbose-http-errors flag and see if there is a more detailed error log. – damianodamiano Oct 2 '18 at 12:06
  • I already tried, and this command is already in both the config.ini and the script to start the node; but I cannot see any difference in the error output. – Riccardo Persiani Oct 2 '18 at 12:07
  • But are you able to access the table using cleos? – damianodamiano Oct 2 '18 at 12:11
  • I can access the table, but there is no content inside. The previous content - of the old table before renaming - is no more there. – Riccardo Persiani Oct 2 '18 at 12:12
  • I think you should post some code smippets you have changed to get mor help... – damianodamiano Oct 2 '18 at 12:15

It took me a while, but I finally solved the issue.

Searching on Google for this kind of error, the most interesting source I was able to find was the following: https://github.com/EOSIO/eos/issues/4394.

The issue described at the link is not the same as mine, but actually suggested me that there was something wrong when calling an action, from a smart contract.

In fact, the error was in the parameters that I was passing, which where not matching with the action called.
