Generates invalid functions? about ajv-errors

[nabati]

For the sake of future travellers:

I didn't pinpoint the exact root cause of this issue, but my best guess is that it was due to some dependency getting linked together in an incorrect way.

We are using a mono repo setup, and adding nohoist to the root-most package.json resolved seems to have resolved this issue;

  "workspaces": {
    "packages": [
      "apps/*",
     ],
    "nohoist": ["**/ajv*", "**/ajv*/**"]
  },

Running this in another repo, same version of the libraries as far as I can see, but getting a different result. Not sure what the issue could be 🤔

async function validate14(data, {instancePath="", parentData, parentDataProperty, rootData=data}={}){let vErrors = null;let errors = 0;if(data && typeof data == "object" && !Array.isArray(data)){if(data.title !== undefined){if(typeof data.title !== "string"){const err0 = {instancePath:instancePath+"/title",schemaPath:"#/properties/title/type",keyword:"type",params:{type: "string"},message:"must be string"};if(vErrors === null){vErrors = [err0];}else {vErrors.push(err0);}errors++;}if(errors > 0){const emErrs0 = [];for(const err1 of vErrors){if(((((err1.keyword !== "errorMessage") && (!err1.emUsed)) && ((err1.instancePath === instancePath+"/title") || ((err1.instancePath.indexOf(instancePath+"/title") === 0) && (err1.instancePath[instancePath+"/title".length] === "/")))) && (err1.schemaPath.indexOf("#/properties/title") === 0)) && (err1.schemaPath["#/properties/title".length] === "/")){emErrs0.push(err1);err1.emUsed = true;}}if(emErrs0.length){const err2 = {instancePath:instancePath+"/title",schemaPath:"#/properties/title/errorMessage",keyword:"errorMessage",params:{errors: emErrs0},message:"this is an error message"};if(vErrors === null){vErrors = [err2];}else {vErrors.push(err2);}errors++;}const emErrs1 = [];for(const err3 of vErrors){if(!err3.emUsed){emErrs1.push(err3);}}vErrors = emErrs1;errors = emErrs1.length;}}}else {const err4 = {instancePath,schemaPath:"#/type",keyword:"type",params:{type: "object"},message:"must be object"};if(vErrors === null){vErrors = [err4];}else {vErrors.push(err4);}errors++;}if(errors === 0){return data;}else {throw new Error0(vErrors);}}

Relevant parts are translated to the following instead.

emErrs0.push(err1);
err1.emUsed = true;

Any idea why this could be?

I've seen this too. For me it happens when I've transpiled my ES6 usage with babel.
