firebase dataconnect:sdk:generate fails with "unexpected error" #9942
Description
firebase-tools version: 15.6.0
firebase.json:
{
"dataconnect": {
"source": "dataconnect"
}
}
dataconnect/dataconnect.yaml:
location: us-central1
schema: schema/schema.gql
connector: gcp-postgresql
dataconnect/schema/schema.gql:
Data Connect schema for the Flooring Quote Pro application.
The 'Query' type defines the entry points for read operations.
While Data Connect auto-generates queries for tables, the type must be declared.
type Query {
Placeholder to ensure the Query type is valid.
_placeholder: String
}
The 'User' table stores information about the application's users.
It is keyed by the Firebase Auth UID.
type User @table {
id: String! @default(expr: "auth.uid")
email: String! @unique
createdAt: Timestamp! @default(expr: "request.time")
updatedAt: Timestamp! @default(expr: "request.time")
}
The 'Project' table stores information about the projects created by users.
type Project @table {
id: UUID! @default(expr: "uuidV4()")
user: User!
projectName: String!
projectType: String
createdAt: Timestamp! @default(expr: "request.time")
updatedAt: Timestamp! @default(expr: "request.time")
}
The 'Quote' table stores the quotes generated for each project.
type Quote @table {
id: UUID! @default(expr: "uuidV4()")
project: Project!
quoteData: String
createdAt: Timestamp! @default(expr: "request.time")
updatedAt: Timestamp! @default(expr: "request.time")
}
The following are custom mutations added to the schema.
type Mutation {
Updates the name of a project.
updateProject(id: UUID!, projectName: String!): Project
@auth(level: "private")
@db(kind: "postgresql", statement: """
UPDATE projects
SET project_name = :projectName, updated_at = now()
WHERE id = :id AND user_id = :auth.uid
RETURNING *;
""")
Deletes a project.
deleteProject(id: UUID!): Project
@auth(level: "private")
@db(kind: "postgresql", statement: """
DELETE FROM projects
WHERE id = :id AND user_id = :auth.uid
RETURNING *;
""")
}
Debug Output:
[2026-02-18T21:37:12.060Z] TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received undefined
