SyntaxError: Unexpected token u in JSON at position 0 when loading flight plan from simbrief

any idea how to fix this?

Hi…,

Welcome.

What are you loading flight plan into? Please upload flight plan.

Cheers

Continuing the discussion from SyntaxError: Unexpected token u in JSON at position 0 when loading flight plan from simbrief:

I have been getting same errors for days regardless of what flight plan I load. Here is my latest flight planLSZBLFMV_MFS_24Aug21.pln (7.4 KB)

Bump, the same problem.
“SyntaxError: Unexpected token u in JSON at position 0” after loading SimBrief Flight Plan.

I found a problem.
There is a “mix” of Airways (UN127-UN128) and Navigraph doesn’t see it (or Simbrief is wrongly creating Flight Plan)

Please upload flightplan.

The issue went away since I sent this email. Error has not shown since.

It just started for me; first time. Tried to do an auto route from PANC to CYFB, BGTL being the alternate. During the calculation I get this error.

Hi.,

We have identified the issue and will shortly be releasing a fix.
