Unhandled Promise Rejection Warning in tahoma.js

[hmwelsch]

I get the following error message which seems to be a message for nikkow?

(node:32106) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'finished' of undefined

(node:32106) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag --unhandled-rejections=strict (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 448)
(node:32106) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
