Failed to read mobile payload file: ${filePath} (status ${re

Error message

Failed to read mobile payload file: ${filePath} (status ${response.status})

What it means

Thrown when the fetch of a locally converted file URL (Capacitor.convertFileSrc) for a mobile token payload returns a non-ok HTTP status, meaning the webview bridge could not serve the file from the device cache (missing file or access failure).

Solutions

1. Confirm the payload file still exists in the cache directory and retry the read.
2. Handle non-200 responses by re-uploading the payload or surfacing the server error to the user.

When it happens

Trigger: Thrown in readTokenPayload when fetching the cached blob file via Capacitor.convertFileSrc returns a non-OK HTTP status, so the payload bytes cannot be read.

Common situations: Happens when the cached blob file was evicted or the OS denies access. decodePayload can retry through the onTokenReadFailure callback to fetch a fresh payload.
