I need to create a lookup field with pnpjs that allows multiple values. I tried adding the following

`
await list.fields.addLookup('myLookUpListName', 'GUID VALUE', 'Title', {AllowMultipleValues:true});

but get the error:
The property 'AllowMultipleValues' does not exist on type 'SP.FieldCreationInformation'
`
but can see that there is no type in the FieldCreationProperties to cover the multiple values.

Is there another way to create lookup with pnpjs that allows multiple values?

You need to make two requests. As the error tells you the AllowMultipleValues is not available when you initially create the field.

const fieldAddResult = await sp.web.fields.addLookup("Test Lookup 124", "GUID", "Title");

await fieldAddResult.field.update({
    AllowMultipleValues: true,
}, "SP.FieldLookup");
