No such address space: %s

Error message

No such address space: %s

What it means

Ghidra DebuggerGoToTrait.tryAddress() looks up the named address space via factory.getAddressSpace(spaceName); if it returns null the method throws IllegalArgumentException. This is the platform/address-factory path used before falling back to Sleigh expression evaluation.

Solutions

1. Use a space name that exists for the current platform: enumerate via factory.getAddressSpaces().
2. Let the offset be resolved without an explicit space, or use the register/ram convention for the active language.
3. Switch to a trace whose language provides the expected space.
4. Catch IllegalArgumentException and report available spaces to the user.

Example fix

// before
Address a = tryAddress(factory, "mem", "1000"); // 'mem' not defined -> throws

// after
String space = factory.getDefaultAddressSpace().getName(); // e.g. "ram"
Address a = tryAddress(factory, space, "1000");

AddressSpace space = factory.getAddressSpace(spaceName);
if (space == null) {
    // list valid spaces: factory.getAddressSpaces()
    return;
}

boolean spaceExists(ghidra.program.model.address.AddressFactory f, String name) {
    return f.getAddressSpace(name) != null;
}

try {
    Address a = tryAddress(factory, spaceName, offset);
} catch (IllegalArgumentException ex) {
    // 'No such address space'; pick factory.getDefaultAddressSpace()
}

When it happens

Trigger: A Go-To request names an address space that the current platform's AddressFactory does not provide (e.g., 'ram' vs 'mem' vs 'register'), or a typo in the space name.

Common situations: Trace's language defines different space names than the user typed; cross-language copy-paste of an address expression; stale plugin state after switching traces.
