here is the function that throws the error (compiled in js)
this.buildResolversMetadata(definitions);
definitions.forEach(def => {
def.roles = this.findFieldRoles(def.target, def.methodName);
def.getObjectType =
def.kind === "external"
? this.resolverClasses.find(resolver => resolver.target === def.target).getObjectType
: () => def.target;
if (def.kind === "external") {
const objectTypeCls = this.resolverClasses.find(resolver => resolver.target === def.target)
.getObjectType();
const objectType = this.objectTypes.find(objTypeDef => objTypeDef.target === objectTypeCls);
const objectTypeField = objectType.fields.find(fieldDef => fieldDef.name === def.methodName);
if (!objectTypeField) {
if (!def.getType || !def.typeOptions) {
throw new errors_1.NoExplicitTypeError(def.target.name, def.methodName);
}
const fieldMetadata = {
name: def.methodName,
schemaName: def.schemaName,
getType: def.getType,
target: objectTypeCls,
typeOptions: def.typeOptions,
deprecationReason: def.deprecationReason,
description: def.description,
roles: def.roles,

};
this.collectClassFieldMetadata(fieldMetadata);
objectType.fields.push(fieldMetadata);
}
else {
if (objectTypeField.params.length === 0) {
objectTypeField.params = def.params;
}
if (def.roles) {
objectTypeField.roles = def.roles;
}
else if (objectTypeField.roles) {
def.roles = objectTypeField.roles;
}
}
}
});
}Somehow the following line is producing an undefined object:
const objectType = this.objectTypes.find(objTypeDef => objTypeDef.target === objectTypeCls);
