could not write token to disk %w

Error message

could not write token to disk %w

What it means

Raised in writeMetaDataToDisk when yaml.Marshal fails to serialize the Pocket access-token metadata before it is written to pocket.data in the wtf config dir. Marshal of a simple struct rarely fails; the more misleading part is that the error is also produced at this single point even though the actual disk write happens later — check the wrapped error for the real cause.

Solutions

1. Inspect the wrapped error (%w) to identify the serialization failure
2. Ensure the wtf config directory exists and is writable so the subsequent write can succeed
3. Re-run the Pocket authorization flow if the stored token metadata is missing or corrupt
