I see no problem with the fix.

However I encountered the same issue before and its the reason behind #2375 that I thought solved the problem.
@ayrat555 did you encounter the error after this PR was merged?

@pasqu4le

However I encountered the same issue before and its the reason behind #2375 that I thought solved the problem.

ah, #2375 is not a part of release yet. Thanks for noticing that. This error was from the production instance where that fix is not installed yet. Then I suggest postponing merging the current PR and try #2375 first if @ayrat555 has no objections.

[vbaranov]

I am closing this PR for now. After installing 2.0.2 there is no more such error on Kovan instance.
