Query: Robustness of a plasma acceleration based Free Electron Laser   Laser Plasma Accelerators (LPA) can sustain GeV/m accelerating fields
offering outstanding new possibilities for compact applications. Despite the
impressive recent developments, the LPA beam quality is still significantly
lower than in the conventional radio-frequency accelerators, which is an issue
in the cases of demanding applications such as Free Electron Lasers (FELs). If
the electron beam duration is below few tens of femtosecond keeping pC charges,
the mrad level divergence and few percent energy spread are particularly
limiting. Several concepts of transfer line were proposed to mitigate those
intrinsic properties targetting undulator radiation applications. We study here
the robustness of the chromatic matching strategy for FEL amplification at
200~nm in a dedicated transport line, and analyze its sensitivity to several
parameters. We consider not only the possible LPA source jitters, but also
various realistic defaults of the equipment such as magnetic elements
misalignements or focussing strength errors, unperfect undulator fields, etc...
