5  mappings: [
6    {
7      from: /^\/toolbox/,
8      to: '/arcgis/rest/services/Electrofishing/Toolbox/GPServer',
9      secrets: 'ARCGIS_SERVER_CREDENTIALS',
10    },
11    {
12      from: /^\/mapservice/,

19      secrets: 'ARCGIS_SERVER_CREDENTIALS',

21  ],
22  claimsCheck: (claims) => {
23    if (process.env.FUNCTIONS_EMULATOR) {
24      return true;
25    }
26
27    return !!claims.firebase?.sign_in_attributes?.customClaim;
28  },
29};
30
31const [proxy, secrets] = initProxy(options);
32
33export const maps = functions.runWith({ secrets }).https.onRequest(proxy);

host and mappings are required but checkClaims is optional. secrets must match the name of a Firebase Functions secret.

Set option verbose: true to turn on verbose logging.
