Can't configure the test network settings

Question

I am trying to Configure the test network settings. I am following this tutorial.

This is my config.toml file

[relaychain]

default_command = "./binaries/polkadot/polkadot"
default_args = ["-lparachain=debug"]

chain = "rococo-local"

[[relaychain.nodes]]
name = "alice"

[[relaychain.nodes]]
name = "bob"

[[relaychain.nodes]]
name = "charlie"

[[relaychain.nodes]]
name = "dave"

[[parachains]]
id = 1000
cumulus_based = true

[parachains.collator]
name = "parachain-A-1000-collator01"
command = "./binaries/parachain-template/parachain-template-node"

[[parachains]]
id = 1001
cumulus_based = true

[parachains.collator]
name = "parachain-B-1001-collator01"
command = "./binaries/parachain-template/parachain-template-node"

When I start test network using ./zombienet-macos spawn config.toml -p native command, network is started but I get this warning,

(node:28868) ExperimentalWarning: The Fetch API is an experimental feature. This feature could change at any time
(Use `zombienet-macos --trace-warnings ...` to show where the warning was created)

Why I am getting this warning? How to fix this or should I ignore?

and after some time it terminate automatically with this error,

Switch to release-v1.0.0 branch and recompile. This is due to the fact that on master, since this PR, polkadot has two other binaries (workers) that you need to compile.
