ECCODES Error Code 250

If you get an error message from ECCODES with code 250, locking like this:

ECCODES ERROR   :   wrong size (184) for pv it contains 276 values
ECCODES ERROR   :  get: pv Passed array is too small
... ERROR CODE: 250
... ERROR MESSAGE:
         Command '['<path-to-flex_extract>/flex_extract_v7.1/Source/Fortran/calc_etadot']' returned non-zero exit status 250.
... FORTRAN PROGRAM FAILED!

then you have set a wrong maximum level in the CONTROL file! It is important to properly select the maximum level depending on the data set you would like to retrieve. The following model level definitions (number of model levels available) are limited to [16, 19, 31, 40, 50, 60, 62, 91, 137]. The ERA-Interim data set uses 62 model levels and ERA5 as well as CERA-20C uses 137. The operational data set uses different model levels depending on the date. For example, on the 25/06/2013 the operational system started to use 137 model levels. Therefore, everytime you extract data from a date later than 25/06/2013 you have to select LEVEL=137 in the CONTROL file or define a LEVELLIST=1/to/137. Of course you can stop before the top of the atmosphere, such as 60/to/137, but you have to select the maximum level number as the last one. Table 2 in the scientific model description paper gives an overview of the level lists and the corresponding introducstion date.
