SyntaxError issue while running spectral lint

[lucas-silveira]

Describe the bug
I'm getting a SyntaxError issue while running spectral-lint library.

Unfortunately I cannot share my OpenAPI document because it's a private project. But it's an OpenApi 3.0.0 version. It's not broken (I've already test it in the Swagger Editor).

I suspect that it may be some dependency with a version conflict, since in another project the lib works (with the same document as the problematic project). Both projects use the Node v20.9.0 version.

Expected behavior
When running the npx spectral lint -r myruleset.yaml openapi.json command, validate the document and return the result.

Screenshots
The error is the following:

Error compiling schema, function code: const schema16 = scope.schema[10];return function validate14(data, {instancePath="", parentData, parentDataProperty, rootData=data}={}){let vErrors = null;let errors = 0;if((!(data && typeof data == "object" && !Array.isArray(data))) && (data !== null)){const err0 = {instancePath,schemaPath:"#/type",keyword:"type",params:{type: schema16.type},message:"must be object,null"};if(vErrors === null){vErrors = [err0];}else {vErrors.push(err0);}errors++;}if(data && typeof data == "object" && !Array.isArray(data)){for(const key0 in data){if(!(key0 === "keyedBy")){const err1 = {instancePath,schemaPath:"#/additionalProperties",keyword:"additionalProperties",params:{additionalProperty: key0},message:"must NOT have additional properties"};if(vErrors === null){vErrors = [err1];}else {vErrors.push(err1);}errors++;}}if(data.keyedBy !== undefined){if(typeof data.keyedBy !== "string"){const err2 = {instancePath:instancePath+"/keyedBy",schemaPath:"#/properties/keyedBy/type",keyword:"type",params:{type: "string"},message:"must be string"};if(vErrors === null){vErrors = [err2];}else {vErrors.push(err2);}errors++;}}}if(errors > 0){const emErrors0 = {"type":[]};for(const err3 of vErrors){if(((((({"str":"err3"}.keyword !== "errorMessage") && (!{"str":"err3"}.emUsed)) && ({"str":"err3"}.instancePath === instancePath)) && ({"str":"err3"}.keyword in {"str":"emErrors0"})) && ({"str":"err3"}.schemaPath.indexOf("#") === 0)) && (/^\/[^\/]*$/.test({"str":"err3"}.schemaPath.slice(1)))){{"str":"emErrors0"}[{"str":"err3"}.keyword].push({"str":"err3"});{"str":"err3"}.emUsed = true;}}for(const key1 in emErrors0){if({"str":"emErrors0"}[{"str":"key1"}].length){if(vErrors === null){vErrors = [{"str":"err4"}];}else {vErrors.push({"str":"err4"});}errors++;}}const emErrs0 = [];for(const err5 of vErrors){if(!{"str":"err5"}.emUsed){{"str":"emErrs0"}.push({"str":"err5"});}}vErrors = emErrs0;errors = {"str":"emErrs0"}.length;}validate14.errors = vErrors;return errors === 0;}

Library version
I've tested the following @stoplight/spectral-cli versions:

• 6.13.0
• 6.12.0
• 6.11.0

Update

I found that this problem occurs when using the cli with @stoplight/spectral-core:1.19.1. When installing the @stoplight/spectral-core:1.18.3 version directly the problem no longer occurs.

I solved it by updating this npm update @stoplight/spectral-core ajv
