Using removeOwner of a gnosis safe doesnt seem to work for the first owner of the linked list

Supposing we have an array of owners ["0x8...09","0x3...26","0x2...9d"] There doesnt seem to be a possibility of removing using removeOwner the owner "0x8...09" as setting the prevOwner to 0x0000000000000000000000000000000000000000 fails.

Seems to be a bug? or what needs to be supplied as prevOwner to remove the first element ?

You should supply the sentinel node:

Thank you, for others in the future, that has indeed solved it by using "0x0000000000000000000000000000000000000001" as you mentioned
