We have a situation where a user accidentally used a ‘|‘ character in the name of a tag provider and now the gateway throws null pointer exceptions and it won’t start up.
And there seems to be no way of fixing it?
This was with 8.3.0 - I could not find anything in changelogs to determine whether this has been fixed in a later version?
Couldn’t it be fixed so that the system prevents storing an invalid character when the consequences are so dramatic? Maybe a whitelist of acceptable characters?
To rectify this issue and get your system starting again, you can rename the folder for that tag provider in data/config/resources/core/ignition/tag-provider
I just tested it in 8.3.1 and could still reproduce the issue, though only on Windows. As Kyle mentions, rename the folder from foo%7c (which will be what you'll see if the tag provider is named foo|) to foo. Then go to Platform -> System -> Modes and click the Scan File System button in the upper-right. This will re-read the config and start up the tag provider, now with a valid name.
