electrs is missing /data/.bitcoin/.cookie

[TylonHH]

I am experiencing issues with Electrs on my Umbrel node and would appreciate assistance. My setup includes Umbrel version 1.3 running on a Raspberry Pi 5 with 8GB RAM and a 2TB SSD. Bitcoin is fully synchronized, and the Lightning Network is functioning correctly. However, when attempting to connect Sparrow Wallet to Electrs, I encounter the following problem:

Electrs displays the message: "Connecting to Electrs server…" continuously.

Here is the relevant log output:

electrs_electrs_1    | Starting electrs 0.10.7 on aarch64 linux with Config { network: Bitcoin, db_path: "/data/db/bitcoin", db_log_dir: None, daemon_auth: CookieFile("/data/.bitcoin/.cookie"), daemon_rpc_addr: 10.xxx.xxx.8:8332, daemon_p2p_addr: 10.xxx.xxx.8:8333, electrum_rpc_addr: 0.0.0.0:50001, monitoring_addr: 127.0.0.1:4224, wait_duration: 10s, jsonrpc_timeout: 15s, index_batch_size: 10, index_lookup_limit: None, reindex_last_blocks: 0, auto_reindex: true, ignore_mempool: false, sync_once: false, skip_block_download_wait: false, disable_electrum_rpc: false, server_banner: "Umbrel Electrs (0.10.7)", signet_magic: f9beb4d9 }

It appears that Electrs is unable to locate the bitcoind cookie file at /data/.bitcoin/.cookie. I suspect there might be a configuration issue causing this problem since it should use rpc, shouldn't? Has anyone encountered a similar issue or can provide guidance on resolving this?

Thank you in advance for your assistance.

So how do I tell electrs to use the RPC instead of the .cookie?
