Nebula 3.4.1, query statement as below:
upsert edge on friend "14"->"15"@31 set descr=SPLIT(descr,",")+",1"
The above statement prompts "Storage Error: Invalid data, may be wrong value type."
I want to process the descr field by splitting it and taking the first element. What can I do? Is the UPSERT statement not supporting the split function?
