How do I update a skillset successfully in azure cognitive search

I updated a TextSplitSkill using the skillsetblade in the azure portal and I got an empty bracket as an output. After the mapping of the index with the indexer, my skillset in the index json came out empty i.e ""mypages": []

This is my skillset.json below
