Custom snap Guice error
Hi, We are facing the following error with my custom snap. Has anyone faced this error, is this a known issue? My custom snap pack is a simple one with a snap and an account. Seems like the account injection is failing at certain point, a restart resolves the issue for a while and then the issue appears again out of the blue. First I thought it could be because the snap pack were deployed at multiple project, but then we cleaned it up and now snap pack is deployed only on the root shared folder, still we are facing the error. Any clue?
