Checked for duplicates

Is this a regression?

No - This is a new bug

Version

4.2.1

Describe the bug

If a sequence filter is generated with a subsystem filter, it cannot be used/applied and gives the following error:

ERROR app - dimension values cannot be null
error: dimension values cannot be null
     at Parser.parseErrorMessage (/app/node_modules/pg-protocol/dist/parser.js:287:98)
     at Parser.handlePacket (/app/node_modules/pg-protocol/dist/parser.js:126:29)
     at Parser.parse (/app/node_modules/pg-protocol/dist/parser.js:39:38)
     at Socket.<anonymous> (/app/node_modules/pg-protocol/dist/index.js:11:42)
     at Socket.emit (node:events:517:28)
     at addChunk (node:internal/streams/readable:368:12)
     at readableAddChunk (node:internal/streams/readable:341:9)
     at Readable.push (node:internal/streams/readable:278:10)
     at TCP.onStreamRead (node:internal/stream_base_commons:190:23)

Reproduction

1. Create a sequence filter
2. Add a subsystem filter
3. Mouse-over and click 'Apply Filter'
4. Error should appear with failure toast
