The solution did not resolve it for me
I ran into the same issue. The solution proposed at https://stackoverflow.com/questions/72695038/appsync-simulator-typeerror-cannot-convert-undefined-or-null-to-object (downgrading cfn-resolver-lib from 1.1.8 to 1.1.7) did resolve the issue in my case.
Thank you for responding
I finally fixed it..
Had to switch to npm
and remove serverless-plugin-typescript
>.<
I don't have serverless-plugin-typescript
installed here. How did you guys solve this?
Just started a new project and get this error also. Any updates?
I'm using yarn, so I added the following to my package.json to force the use of the previous version of cfn-resolver-lib:
"resolutions": {
"serverless-appsync-simulator/cfn-resolver-lib": "1.1.7"
}
Not sure what the equivalent would be with npm.
Another option is to update serverless-appsync-simulator/lib/index.js
resolveResources(toBeResolved) {
// Pass all resources to allow Fn::GetAtt and Conditions resolution
const node = { ...this.serverless.service.resources,
toBeResolved,
Parameters: {}, // Passing {} would avoid the issue on latest cnf-resolver-lib version
};
const evaluator = new _cfnResolverLib.default(node, this.resourceResolvers);
const result = evaluator.evaluateNodes();
if (result && result.toBeResolved) {
return result.toBeResolved;
}
return toBeResolved;
}
Thank you @katesclau
Could you open a PR to fix this? That would be great.
Thanks
in npm I just installed cfn-resolver-lib "1.1.7" explicitly and it helped
I can also confirm adding:
npm i cfn-resolver-lib@1.1.7 --save-dev
solves the issue!
