Failed to parse auth config update data

Error message

Failed to parse auth config update data

What it means

ValidationError from AuthConfigs.update: the data argument failed AuthConfigUpdateParamsSchema before the update body is built. Different update types (e.g. custom) produce different required field sets, and the discriminated union rejects mismatches.

Solutions

1. Check error.cause ZodError issues for required/invalid fields
2. Match all fields required by the type discriminator you're sending
3. Fetch the current auth config and derive the update payload from it
4. Use the exported AuthConfigUpdateParams TS type

Example fix

// before
authConfigs.update(id, { type: 'custom', creds: 'token' } as any);
// after
authConfigs.update(id, { type: 'custom', creds: { key: 'API_KEY', value: '...' } });

import { AuthConfigUpdateParamsSchema } from '@composio/core';
const check = AuthConfigUpdateParamsSchema.safeParse(data);
if (!check.success) console.error(check.error.issues);

const validUpdateData = (d: unknown): boolean =>
  AuthConfigUpdateParamsSchema.safeParse(d).success;

try { await authConfigs.update(id, data); } catch (e) { if (e instanceof ValidationError && e.message.includes('auth config update')) fixFromZodIssues(e.cause); }

When it happens

Trigger: authConfigs.update(nanoid, { type: 'custom', ... }) missing required custom fields; passing fields that belong to a different auth type; updating with a stale shape after the API contract changed.

Common situations: Updating legacy auth configs after SDK upgrades; merging partial patches that drop required discriminator fields; automated scripts reusing create payloads for updates.

Understand the failure class

Background: Schema validation failed / invalid input schema: payload rejected because its shape doesn't match the expected schema — this error's family across 28 libraries.

• Parsing and encoding errors: unexpected token, malformed input — why parsers reject input and how to find the real culprit.
