Is there an existing issue for this?

Current behaviour
On my Ubuntu 24.04 system on running rpc_signer.py functional test (after compiling from source) fails the test which tests the case of missing script (on master and 28.x but passes on 27.x !) I tried running (with only regtest = 1 in bitcoin.conf)
0bitcoind -daemon -signer=fake.py
1bitcoin-cli enumeratesigners
to get the following:
0execve failed: Not a directory (20)
which is different than what is asserted in the test. I tried compiling 28.x and master on a Ubuntu 24.04 VM running on Qemu/KVM and the test passes there.
I followed all the steps for installing the dependencies mentioned in build-unix.md and checked the versions mentioned in dependencies.md . Also tried removing bitcoin and again compiling from source but the test still fails.
Expected behaviour
The functional test should pass just like it does on the CI.
Steps to reproduce
I referred to build-unix.md for compile instructions and installing dependencies. For master followed the following commands:
0cmake -B build
1cmake --build build
2cmake --install build
3build/test/functional/rpc_signer.py
which gives basically the following error:
0Traceback (most recent call last):

2 self.run_test()

12error message: 'execve failed: Not a directory (20)'.
For 28.x and 27.x (used git worktree to create separate directories and then git reset hard to overwrite with upstream/28.x and upstream/27.x):
0./autogen.sh
1./configure
2make
3test/functional/rpc_signer.py
28.x gives similar error as master but 27.x passes!

running bitcoind with the -signer=fake.py and then getting strace output on running enumeratesigners rpc gave only the following major differences on master and 27.x
on master:
0readv(6, [{iov_base="HTTP/1.1 200 OK\r\nContent-Type: application/json\r\nDate: Sat, 14 Dec 2024 09:31:05 GMT\r\nContent-Length: 93\r\nConnection: close\r\n\r\n{\"jsonrpc\":\"2.0\",\"error\":{\"code\":-1,\"message\":\"execve failed: Not a directory (20)\"},\"id\":1}\n", iov_len=220}], 1) = 220
on 27.x
0readv(6, [{iov_base="HTTP/1.1 500 Internal Server Error\r\nContent-Type: application/json\r\nDate: Sat, 14 Dec 2024 09:32:19 GMT\r\nContent-Length: 96\r\nConnection: close\r\n\r\n{\"result\":null,\"error\":{\"code\":-1,\"message\":\"execve failed: No such file or directory\"},\"id\":1}\n", iov_len=242}], 1) = 242
but on doing the same for master and 28.x on a VM(Ubuntu 24.04.1 LTS on VirtualBox) gave the same strace output as my system but with the correct error message.
PS: The logs/outputs mentioned for master(except for the first one in this section) are old and not for master-b042c4f0538c
