The resulting squid should match the GraphQL API of the subgraph as close as possible, by migrating `schema.graphql`. The judges reserve the right to request improvements afther the initial review of the submission. Reach out to the [Discord Channel]( https://discord.com/channels/857105545135390731/1155812879770058783) for any tech questions regarding this quest. # Quest Info | Category | Skill Level | Time required (hours) | Max Participants | Reward | Status | | ---------------- | ------------------------------------ | --------------------- | ---------------- | ---------------------------------- | ------ | | Squid Deployment | $\textcolor{green}{\textsf{Intermediate}}$ | ~10 | 5 | $\textcolor{red}{\textsf{1500tSQD}}$ | closed | # Acceptance critera Each quest should be submitted as a private repo and will be reviewed manually. To submit, create an issue with url to your repo and invite the following github accounts: [@dariaag](https://github.com/dariaag), [@belopash](https://github.com/belopash), [@abernatskiy](https://github.com/abernatskiy) and [@dzhelezov](https://github.com/dzhelezov). The repo should contain `README.MD` with - Insturctions how to run the squid locally - Sample Squid queries and the corresponding Subgraph queries The code should be well documented. The judges will access: - In-line commends where necessary - Clarity of the code - Performance and optimization (if [batching](https://docs.subsquid.io/basics/batch-processing/) and [Multicall queries](https://docs.subsquid.io/tutorials/bayc/step-four-optimizations/#using-multicall-for-aggregating-state-queries) are used whenever appropriate) # Useful links - [Quickstart](https://docs.subsquid.io/deploy-squid/quickstart/) - [TheGraph Migration guide](https://docs.subsquid.io/migrate/migrate-subgraph/) - [Snapshot Subgraph source code](https://github.com/snapshot-labs/snapshot-subgraph) # Setup and Common errors 1. Install Node v16.x or newer [https://nodejs.org/en/download](https://nodejs.org/en/download) 2. Install Docker [https://docs.docker.com/engine/install/](https://docs.docker.com/engine/install/) 3. Install git [https://git-scm.com/book/en/v2/Getting-Started-Installing-Git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git) 4. Install Squid CLI ```bash npm i -g @subsquid/cli@latest ``` ## How to run a squid: 1. Install dependecies: ```bash npm ci ``` 2. Generate model ```bash sqd codegen ``` 3. Generate types ```bash sqd typegen ``` 4. Open docker and run: ```bash sqd up ``` 5. Generate migrations: ```bash sqd migration:generate ``` 6. Start processing: ```bash sqd process ``` ## Possible Errors: 1. Docker not installed ```bash X db Error × query-gateway Error Error response from daemon: Get "https://registry-1.docker.jo/v2/": uri ting to 127.0.0.1:8888: dial cp 127.0.0.1:8888: connectex: No connection ``` 2. Git not installed ```bash Error: Error: spawn git ENOENT at ChildProcess._handle.onexit (node: internal/child_process: 284:19) at onErrorNT (node: internal/child_process:477:16) at process.processTicksAndRejections (node: internal/process/task_queues:82:21) ``` 3. Dependencies not installed. Run `npm ci` ```bash sqd typegen TYPEGEN Error: spawn squid-evm-typegen ENOENT Code: ENOENT ``` 4. Rate-limiting. Change the `rpcUrl` in `processor.ts` ```bash will pause new requests for 20000ms {"rpcUrl":"https://rpc.ankr.com/eth", "reason" : "HttpError: got 429 from https://rpc.ankr.com/eth"} ``` ", Assign "at most 3 tags" to the expected json: {"id":"2760","tags":[]} "only from the tags list I provide: []" returns me the "expected json"
