Error in LDLt decomposition while the mesh quality was good

Hi, I want to ask some advice for the error.
I encountered the following error message repeatedly during the simulation, despite having confirmed that the mesh quality was good in the initialization phase.
However, the simulation was finalized, and I obtained the results without any additional error messages.
I’m unsure whether I can safely ignore the error message or if I should adjust certain parameters to ensure the accuracy of the results.

The error message is following :
ERROR in LDLt decomposition in assembPrecontNonLinear =32302
Cathode potential: 31.150644V
Conjugate Gradient (generic, for matrix inversion) reached convergence at iteration 334
Conjugate Gradient (generic, for matrix inversion) reached convergence at iteration 374
Time: 7.4941776E-4, Dt = 1.0E-6 s

The mesh quality is following :
Volume mesh quality
Minimum cell quality:0.24116653
Average cell quality:0.72828114
Overall quality: GOOD, mesh does not impact simulation convergence.

Please give me some advices :cry:
Thank you
