assert: invalid memory address or nil pointer dereference for assert.Error on darwin/arm64

[samanhappy]

I was testing our project on Darwin/arm64, but there were some test failures with the following example log:

=== RUN   TestTwilio
    nexmo_test.go:61: 
        	Error Trace:	/Users/runner/work/easeprobe/easeprobe/notify/sms/nexmo/nexmo_test.go:36
        	            				/Users/runner/work/easeprobe/easeprobe/notify/sms/nexmo/nexmo_test.go:61
        	            				/Users/runner/work/easeprobe/easeprobe/notify/sms/nexmo/nexmo_test.go:87
        	Error:      	An error is expected but got nil.
        	Test:       	TestTwilio
--- FAIL: TestTwilio (0.00s)
panic: runtime error: invalid memory address or nil pointer dereference [recovered]
	panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x2 addr=0x18 pc=0x1047c45a8]

Almost all errors occurred when calling assert.Error like here.

func assertError(t *testing.T, err error, msg string) {
	t.Helper()
	assert.Error(t, err) // Line 36
	assert.Equal(t, msg, err.Error())
}

I'm not sure if this was caused by testify. Does testify support Darwin/arm64? Can you guys help to check it?
