blockFieldSuggestion plugin crashes on errors with undefined message

[strongpauly]

The blockFieldSuggestion plugin's didEncounterErrors handler calls error.message.replace() without checking if error.message is defined, causing a TypeError when Apollo Server encounters a GraphQL error with an undefined message.

Stack trace:

  TypeError: Cannot read properties of undefined (reading 'replace')
      at Object.didEncounterErrors (node_modules/@escape.tech/graphql-armor/dist/graphql-armor.cjs.dev.js:63:43)
      at node_modules/@apollo/server/src/requestPipeline.ts:757:31

      at processGraphQLRequest (node_modules/@apollo/server/src/requestPipeline.ts:505:15)

Affected code:

In packages/plugins/block-field-suggestions/src/index.ts, the formatter does:

  error.message.replace(/Did you mean ".+"\?/g, mask).trim();

There is no guard against error.message being undefined or null.

Environment:

• @escape.tech/graphql-armor: 3.2.0
• @apollo/server: 5.x
