@maxceem Can we fix this?

[maxceem]

@vikasrohit yeah, we can try to fix this, though without having a reproducible example we can do it only guessing the root of error, fixing it and waiting if the issue happens again.

[vikasrohit]

Yes, essentially all issues reported by Sentry are kind of this nature where we have to do our best guess using the details shared by Sentry and try to reproduce it on local. Most of the time, we are getting sufficient details from Sentry to reproduce the issue e.g. in this case:

Exact code snippet from Sentry log details:

{snip} Id:r},i=3);var a=this.getRefCodeFromURL();a&&(o.details.utm={code:a}),this.setState({project:(0,d.default)({},o),dirtyProject:(0,d.default)( {snip}

gives us sufficient hint to reproduce it.

[maxceem]

Sum up:

• Looks like line of the error is here https://github.com/appirio-tech/connect-app/blob/dev/src/projects/create/components/ProjectWizard.jsx#L249
  For this issue it would the best to do two things:
• find out the possible root of this issue and add it as a comment to the issue for future references
• instead of hiding the error at the line where this error has been logged, fix the issue as close to the root as possible

[Gauravseta]

@maxceem are these going to be open for pickup soon?

[maxceem]

@Gauravseta they are still under the consideration, but most likely yes.

[PrakashDurlabhji]

@maxceem i will work on this
