WLED preset errors

Configuration
1

Had to restore backed up config & presets for a WLED device and HA is throwing a fit when I use the presets. Searching around revealed it’s likely a corrupted preset json. Did json and utf-8 validations on that and the configuration backups; found no errors. Manually went through the files to the error locations and retyped the characters again; no change. Reset the device and restored the presets using the original API commands without restoring the preset backup. Nothing I’m doing is stopping this error

I’m actually running into the same problem. WLED has no issues importing my fairly basic ~60 presets that were created 2 days ago (current version). As soon as I import the presets, this node goes unavailable in the integration with the error shown above. As the original poster states, it feels like something is malformed. These were carefully backed up as soon as they were created, so I don’t really understand where any corruption could be occurring. WLED is happy with it, but the integration is not happy reading it.
