Wrong Machine Account string. machine account address is not valid for any chain.

here https://github.com/onflow/flow/blob/master/docs/content/node-operation/machine-existing-operator.mdx

in step 1 we got as result string

<nil> DBG encoded public machine account key machineAccountPubKey=2743786d1ff1bf7d7026d693a774210eaa54728343859baab62e2df7f71a370651f4c7fd239d07af170e484eedd4f3c2df47103f6c39baf2eb2a50f67bbcba6a

where 2743786d1ff1bf7d7026d693a774210eaa54728343859baab62e2df7f71a370651f4c7fd239d07af170e484eedd4f3c2df47103f6c39baf2eb2a50f67bbcba6a needed key for step 2.

In step 2 we run:
$./boot-tools/bootstrap machine-account --address 0x1de23de44985c7e7 -o ./bootstrap
But from where you get this 0x1de23de44985c7e7 ?

Because we must use 2743786d1ff1bf7d7026d693a774210eaa54728343859baab62e2df7f71a370651f4c7fd239d07af170e484eedd4f3c2df47103f6c39baf2eb2a50f67bbcba6a !

And when i use similar string i got error:

bootstrap machine-account --address f847b8402b711d84b67d0ecb886e6eee8727c490f9dfa7fc7b7805f0bc98d797a9334ff927fc5d95ca5e3dfeeefdfd44c39aefcd14794dffeb0dd252158ffa101f001e9f02038203e8 -o /var/flow/bootstrap
