TypeError
renderTopLayer(file://./nodemodules/@aha-app/whiteboard/nodemodules/fabric/dist/fabric.js)
Cannot read properties of null (reading 'save')
This is a fabric bug reported here fabricjs#7876
According to the discussion in the github issue, the error is caused by a race condition. The PR https://github.com/fabricjs/fabric.js/pull/7885/files reportedly fixes it.
Just for extra safety and as also discussed in the issue, I added an early exit to the
renderTopLayer
method whenctx
is falsy.Sentry error
