Using oasis.app DAi repayment failed
Using oasis.app and Metamask.
I repaid dai to the vault on https://oasis.app/, tried several times, but the transaction failed.
This is one of the repayment transactions https://etherscan.io/tx/0x7b4eecea75914f9d7f6a56b7939823e10fffe814c269b3e30d4a2659cf8a49a2
“Warning! Error encountered during contract execution [Reverted]” is displayed, but the gas limit for this transaction is obviously sufficient.
In addition, I found that if the repayment amount is relatively small, it will succeed. Like this transaction of more than 1,000 DAI, https://etherscan.io/tx/0x003f68e5b24b8142bc4fb682c1d38599912dd1cf0c02479dbae940b00855306d will fail.
What is the issue and how do I solve this? Please help, thanks！
