Upgrade to v0.35.0-rc1 using heroku makes Metabase unavailable on Chrome

Hi everyone,

I’ve upgraded Metabase to the latest version using heroku.

The latest Beta version was deployed, and I can’t open metabase using Chrome (that are setup with other languages than English), there’s an empty white screen with the following error in the console:

Uncaught Error: Errors detected in definition of Lexer:
Token: ->Somme cumulée<- can never be matched.
Because it appears AFTER the Token Type ->Somme<-in the lexer's definition.
See https://sap.github.io/chevrotain/docs/guide/resolving_lexer_errors.html#UNREACHABLE

After a few researches, I found this issue, that seems to be resolved and merged, but only for the 0.34.3 version which I can’t rollback to.

I have search for solutions to deploy a specific version of Metabase using Heroku but I can’t find any related topic, any clue on how to fix this ?

Thanks a lot for your help !

@xad9119 I would recommend that you roll back to 0.34.3 - there’s an updated documentation for Heroku, which will include a section about pinning:
https://github.com/metabase/metabase/blob/master/docs/operations-guide/running-metabase-on-heroku.md#pinning-metabase-versions

Hi flamber, thanks a lot I had overlooked this piece of documentation. Problem is solved.
