handler errors with serverless enterprise #28

Closed adjohn closed 5 years ago

User reported issue where the handler is being configured differently from how IOpipe sets it, and ends up with a module not found error.

Error when invoking: 

"errorMessage": "Cannot find module './/opt/nodejs/node_modules/@iopipe/iopipe.js'",
"trace": [
"Error: Cannot find module './/opt/nodejs/node_modules/@iopipe/iopipe.js'",
" at Function.Module._resolveFilename (internal/modules/cjs/loader.js:582:15)",
" at Module._require.o.require (/var/task/serverless_sdk/index.js:9:88803)",
" at require (internal/modules/cjs/helpers.js:22:18)",
" at Object.<anonymous> (/var/task/s_appsyncOdsResolver.js:12:23)",
" at Module._compile (internal/modules/cjs/loader.js:701:30)",

" at Function.Module._load (internal/modules/cjs/loader.js:531:3)",
" at Module.require (internal/modules/cjs/loader.js:637:17)"
]
}

Upon investigation, the handler was set incorrectly to s_appsyncOdsResolver.handler instead of /opt/nodejs/node_modules/@iopipe/iopipe.handler

Manually changing the handler via the AWS console to /opt/nodejs/node_modules/@iopipe/iopipe.handler fixed the issue.

I suspect that AppSync plugin could be messing with the handler after we configure it.

Turns out that when using Serverless enterprise, they modify the handler which breaks IOpipe. Modifying the handler above is a workaround but users may lose some functionality from Serverless enterprise.
