What is the authenticity of Dua Tawassul and the version of Hadith Kisa found in mafatih al Jinan? Are they from an imam?

Despite discussions on the chain of narrators of the mentioned Duas and hadith, shia Ulema generally accept them and recite them, based on a principle known as قاعدة التسامح في ادلة السنن which means we seek God’s pleasure and hope that it’s accepted

Due to the scholars reciting them for hundreds of years, it’s is very important that we keep reciting them, since the meanings contained are in line with Quran and authentic narrations
